4th Cousins on Ancestry.com: a quick study

/ cathmary1030 / Leave a comment

 

Last week in the “Genetic Genealogy Tips & Techniques” group on Facebook, Blaine Bettinger posted a study of his own 4th-cousins-and-closer matches on Ancestry.com which can be viewed here.   I decided to do the same.  These are my results:

Cathy’s 4th cousin (and closer) matches on Ancestry.com

Matches which are included here are matches who, in general, share at least 20 cM of DNA with me (although I have some matches at the 20 cM level who are labeled as “distant” cousins).

The “Amt DNA” information does NOT come from Ancestry; it comes from having done a process called “chromosome mapping” or “visual phasing” and it required the DNA results from both my parents, as well as from my sibs, compared against that of my 1st and 2nd cousins who have tested. On my dad’s side, the amount shared skews towards my grandmother, in part because one of my X chromosomes comes from her and her alone.

The number of matches sharing >= 50 cM with me also skews towards my paternal grandmother because 2 of my dad’s 3 maternal 1st cousins have tested at Ancestry, as well as some of their children and grandchildren. All are no more distant than 2C1R to me. (Note: in that figure I do not include my dad, my sibling, or my paternal 1st cousins — since they share both paternal grandparents with me.)

However, in total numbers of matches, my two grandparents with “colonial” ancestry (and by that I mean roots in the U.S. at least as early as 1790 — but not necessarily as far back as, say, 1650), are the ones with the most matches. That seems to correlate with what I’ve heard from others who have tested at Ancestry. My paternal grandfather has one line — his maternal grandfather — that is “colonial”. My maternal grandmother has 2 lines — both of her maternal grandparents are “colonial”.

I compared the paternal and maternal labeling, but it doesn’t tell me much, in my opinion. Ancestry only labels the DNA match as paternal or maternal if the match is >= 20 cM for both parent and child. Where there are differences in the totals, it is due to the match being >= 20 cM for me, but not for my parent. That’s an artifact of the computer algorithms.

Finally, tree availability in and of itself may not be the be-all end-all for matches. 85% of the matches I identify as paternal unknowns — I cannot discern which grandparent they are kin to — have public trees. The trees have done nothing to help me figure out how that match is related to me! Any suggestions?

On this Day: What were your ancestors doing? – 52 Ancestors #10

/ cathmary1030 / 1 Comment

So, today is my birthday, and taking a hint from other #52Ancestors posts (here, here and here), I wondered what were my ancestors doing on 30 October 1919?

And immediately the question arises — which of my ancestors were alive 100 years ago today? Let’s see… 

This is my dad’s side.  Dad, obviously, was not yet alive; his mom was approaching her 12th birthday.  His dad Cassius was almost 15 and therefore was in high school — the first family member to attend and graduate.   Both of Cassius’ parents were alive, but none of his grandparents.  Margaret’s father William was alive; William’s parents were deceased.  Margaret’s mother Eileen had died, but her grandfather Charles was still alive in Athea, Co. Limerick, where he was a farmer, living with two of his younger children.

Dad_Ancestors

On my mom’s side, both her parents were alive, and living in the Healdsburg, Sonoma, California area.  Each was 5 years old.   Both sets of their parents were living.  I don’t know if Giuseppe Diamantini’s parents were still alive back in Fano, Italy, but possibly not as they would have been born no later than, say, 1852, if not earlier. 

Maria Bolognesi’s parents were dead, and Hazel (Englehart) Holst’s mother had been deceased over a decade.  Peter Holst and his wife Caroline, and Sam Englehart, who crossed the Great Plains to California with his family as a little boy were both still living.  Sam was in Healdsburg, living in the house his late sister had bequeathed him, and working odd jobs.  Peter and Caroline were in the hills just outside Healdsburg, growing grapes and running a small but thriving winery.

Mom_Ancestors

So, in summary, this is the count of my ancestors alive 100 years ago today.

0 – parents

4 – grandparents (ranging in age from 5 to almost 15)

7 – great-grandparents

4 – great-great grandparents

Peter Nicholas Holst’s father reportedly lived to at least 97 years of age; based on Peter’s birth year, I estimated Peter (Sr.) to be born c 1822, and died c 1919 — so he might have been alive on 30 October 1919.  He would have been living in Flensburg, Schleswig-Holstein (Germany now and at the time — but Denmark when he was born).

Part I – My dad’s side

My father’s father 

Name: Cassius Dempsey

Born:  December 1904 in San Francisco

Age: 14

Occupation: high school student

Location: San Francisco, California

Children:  None at the time

Did I know him?  Yes.  He died when I was 31 years old.  I did not see him often, though, as we lived in Florida and Texas in my childhood.  

What was going on in his life at the time?  He was likely in school, and he possibly worked odd jobs after school.  He likely heard about the Chicago “Black Sox” throwing the World Series, and could have played sports at school, or with the neighborhood boys.

Y-Line Haplogroup:  Haplogroup information keeps changing as the science gets better and the data set grows.  Obtained from one of his grandsons, and depending on how you label it, it’s either R-ZS8379 or, further downstream (per http://ytree.net today) R-BY11707.  Closest relatives all have the Molloy surname; historically, the Irish clans of Molloy and Dempsey came from the Co. Offaly area.

mtDNA Haplogroup:  Unknown at this time.

My father’s paternal grandparents

Name: William John Dempsey and Mary Erma Lamburth

Born:  1869 and 1867, respectively, both in San Francisco

Age: 50 and 52, respectively

Occupation: Storekeeper (pump company), and housewife, respectively

Location: San Francisco, California

Children:  7 children; 6 living on 30 October 1919

Did I know them?  No. William died about 6 months after my father was born.  Mary died while my father was still in high school.  

What was going on in their lives at the time?  He was likely in school, and he possibly worked odd jobs after school.  He likely heard about the Chicago “Black Sox” throwing the World Series, and could have played sports at school, or with the neighborhood boys.

Y-Line Haplogroup:  William’s haplogroup was R-ZS8379 (or, more recently) R-BY11707.

mtDNA Haplogroup:  Unknown at this time for either William (who had only brothers) or Mary.

My father’s mother 

Name: Margaret Colbert

Born:  January 1908 in San Francisco

Age: 11

Occupation: student

Location: San Francisco, California

Children:  None at the time

Did I know her?  Yes.  She died on my 22nd birthday.  I did not see her often; the last time was in summer 1976, when I was 14.  

What was going on in her life at the time?  She was probably in school, and lived at home with her 2 older sisters, her younger brother, and her widowed father.  (She was just shy of her 4th birthday when her mother died.)  Her paternal aunt Nan, her paternal uncle Jack, and her maternal aunt Margaret lived near enough that she probably saw them regularly.

mtDNA Haplogroup:  W1c (inferred, based on her son’s test, and grandchildren of her daughter)

My father’s maternal grandfather

Name: William Cornelius Colbert

Born:  January 1877, near Athea, Co. Limerick, Ireland

Age: 42

Occupation: Teamster – municipal works (not sure what that means; it comes from the 1920 census)

Location: San Francisco, California

Children:  4 children; all living on 30 October 1919

Did I know him?  No. William died in October 1931, before my grandmother even married, let alone had her children. 

What was going on in their lives at the time?  

Y-Line Haplogroup:  Unknown at this time.

mtDNA Haplogroup:  Unknown at this time.

My grandmother’s maternal grandfather

Name: Charles Houlihan

Born: about 1832, probably Co. Limerick, Ireland

Age: about 87

Occupation: Farmer

Location: Athea, Co. Limerick, Ireland

Children:  5 children; at least 2 living on 30 October 1919 (in U.S.).  2 more living in Athea as of 1911 who could’ve been alive in 1919.

Did I know him?  No. Charles died in 1924.  In fact, my grandmother never knew him either.

What was going on in their lives at the time?  The daily life of farming in a rural community.  From the census taken in 1911, I know that he was Roman Catholic, and that he was able to read and write, both in English and Irish.

Y-Line Haplogroup:  Unknown at this time.

mtDNA Haplogroup:  Unknown at this time.

To be continued, with my mother’s side…

 

 

 

 

 

Throwback Thursdays #tbt #wedding – Marie (Colbert) O’Donnell, my grand-aunt

/ cathmary1030 / Leave a comment

Here is another wedding photo from my files.  This photo dates from 1931, when my paternal grandmother’s older sister Hanora Marie Colbert married Philip O’Donnell in San Francisco, California.

I have not requested a copy of Aunt Marie’s marriage certificate, but I have found, on familysearch.org, the index to Brides married in San Francisco County in 1931.  She and  Philip A. O’Donnell tied the knot on 29 August 1931 [1].

From left to right, ladies first:  Margaret Colbert (later, Dempsey)  (1908-1983) , my grandmother and youngest sister of Marie; unknown woman; the bride, Hanora Marie (Colbert) O’Donnell (1902-1999); Anita (Colbert) Foley (1903-1996).

From left to right, the men:  Cassius Patrick Dempsey (1904-1993), my grandfather; unknown man; the groom, Philip A. O’Donnell (1901-1961); John Francis Foley (1902-1986); William C. “Babe” Colbert, the only brother of the bride (1910-1999).

Anita and John were married in San Francisco on 23 April 1927 [2].

Triangulation vs. “In Common With”

/ cathmary1030 / Leave a comment

This question came up in one of the posts in Blaine Bettinger’s Facebook Group Genetic Genealogy Tips & Techniques, so I thought I’d give a quick example here that I refer to myself when I get confused.

A man with 3 children, who have all tested, has a match to a 2nd cousin (documented through now through both DNA and traditional genealogy).  He and the 2nd cousin share 11 segments of DNA.

It so happens that all 11 of those segments have passed down to those 3 children, which you can see in the illustration below.  Of those 11 segments shared by their father and his 2nd cousin, Child 1 inherited 4 segments.  Child 2 also inherited 4 segments — but an entirely different four segments than Child 1.  Child 3 inherited 7 of the 11 segments.

The inheritance and sharing is illustrated below, in data pulled from GedMatch.

Inheritance

For purposes of illustration, we’re setting aside the fact that generally, when triangulating to find a common ancestor, we don’t use two full-blooded siblings as 2 of the triangle legs; they are too closely related, and will triangulate on many segments.

That said, Child 1, Child 2 and their 2nd cousin once removed (2C1R) have DNA in common with each other, but no triangulated segments with their 2C1R.  This is because Child 1 shares DNA with 2C1R on chr 6, on chr 12 and 2 segments on chr 15, while Child 2 shares DNA with 2C1R

Child 1, Child 3 and their 2C1R have 3 triangulated segments: on chr 6, on chr 12, and 1 segment of chr 15.

Child 2, Child 3 and their 2C1R also have 3 triangulated segments: on chr 4, on chr 8, and on chr 18.

*******
And that is a quick overview of triangulation vs. in common with.

 

 

William Colbert, First of 13 children : 52 Ancestors in 52 Weeks, #7

/ cathmary1030 / 2 Comments

Prompt for 2019, week 1 — “First”.

My great-grandfather, William Cornelius (aka Willie) Colbert, was the eldest of 13 children.  He was baptized on 31 January 1877, in Moanlena, Mahoonagh Parish, Co. Limerick, Ireland, to Michael Colbert and Hanora Josephine McDermott.[1]  

william colbert baptism record_mahoonagh parish_limerickgenealogy

William had 7 sisters, and 5 brothers, one of whom was Con Colbert, who was executed on 8 May 1916, after the Easter Uprising.[2]  

Sometime in 1890 or early 1891, the family moved from Moanlena to Athea, as William’s youngest two siblings, Dan and Bridget, were baptized at Templetathea West, Athea parish, Co. Limerick.  Williams’ mother Hanora died in childbirth with the last child born, Bridget, on 17 Sep 1892.

As a young adult, Willie became attracted to a young dairy maid named Eileen Houlihan, daughter of Charles Houlihan and Anna Carmody, also of Athea, Co. Limerick.  The story goes that William’s father Michael wanted no part of William being involved with Eileen, so Michael paid the passage for Eileen to go to San Francisco[3], where her older sister Margaret had immigrated to in 1897.[4]

As one might suspect, that got Michael nowhere, as Willie soon headed to San Francisco himself.  I found a passenger record for a William Colbert from Athea, who traveled to New York from Queenstown on the SS Etruria in July 1899, at the age of 22[5].  That fits with what I know of my great-grandfather.  It also fits with the stated immigration date given on the 1910 Federal Census. 

nyt715_76-0252

Here is a zoomed-in look at the same record: 

passlist_zoom

However, what doesn’t fit William is his stated final destination: the home of his sister Maggie Collins, at 513 Hicks Street, Brooklyn, New York.  While William did have a sister Margaret, she was only 15 and living in Ireland in 1899.  And given that Eileen’s sister Margaret was already in San Francisco for roughly 2 years when Eileen traveled to the U.S., Eileen had no reason to stop in Brooklyn either.  In other words, Margaret Houlihan was not Maggie Collins/Cullins.  Finally, William was aiming to meet up with Eileen, so why delay in Brooklyn?  Long story short, this may or may not be “my” William Colbert.  Some facts fit, some do not.

In any case, Willie is not found on the 1901 Irish census, and by November 1901 he had met up with Eileen in San Francisco, as the filing of their marriage license on 7 November 1901 was recorded in the newspaper.[6]

William and Eileen lived fairly close to each other, as the image below indicates. It was a half-mile walk from one house to the other. (The addresses are based on the newspaper article above.)

mapwherewillieandeileenlivedin1901

William Colbert and Eileen (Houlihan) Colbert, my great-grandparents, ca. 1901

Their first child was Marie Honora, born 27 May 1902.  She was followed by Anita in 1903, my grandmother Margaret in 1908 (click here for the profile on her), and William in 1910.[7]

In May 1905, two of William’s siblings, John Michael and Johanna (aka Nan), sailed together on the SS Campania from Queenstown, Co. Cork, Ireland to New York, and then traveled to San Francisco.[8]  John and Nan are listed on rows 2 and 3 of the passenger manifest below, and state their brother William paid their passage, and their ultimate destination was his place in San Francisco.  They, like William, would live the rest of their lives there.

William was naturalized as a U.S. citizen in June 1905; the records were destroyed in the Earthquake of 1906.  In May 1929, he apparently submitted the necessary paperwork for his naturalization to be restored.[8a]

p13-10-court-williamcolbert

Eileen died in December 1911.[9]   William remarried sometime after the 1920 census, in which he is enumerated as a widower[10], and before 30 August 1923, when his daughter Cornelia (aka Connie) was born.[11]  His wife’s true name was Harriet H. (Maley) Buchan, a native of England, but the name given on the birth certificate for Cornelia was Dorothy O’Maley, a native of Scotland.

My grandmother and her brother William (aka Babe) knew the woman as Mrs. Buchan.  Mrs. Buchan had a daughter Dora, roughly my grandmother’s age, and by tracing Dora’s passenger records, I was able to find a link to my great-grandfather’s San Francisco address, helping to tie the two families together even when personal information (names, birthdates) varied.[12]

The family is intact at the time of the 1930 census enumeration.[13]  William is living with “Dorothy” (aka Harriet), and four of his 5 children: Marie, my grandmother Margaret, William, and Cornelia.  Only Anita was not enumerated with the family.

By October 1931, however, my great-grandfather was dead, his body found in the San Francisco Bay.[14]  When I was first finding out more about my great-grandfather’s life, I asked my dad about William’s death.  William died 18 months before my grandmother married, so Dad never him.  He said that accounts varied.

I may have it wrong as to who said what, but my grandmother said it was suicide, one of her siblings said it was murder, and another sibling said it was an accident.  (Or vice versa – maybe my grandmother was the one who said it was an accident.) 

The idea that it might be suicide came from the fact that “Dorothy” (aka Harriet) had reportedly taken off to Shanghai, China, with little Connie, and Willie was going to go after her.

The idea that it might be murder came from the fact that my great-grandfather reportedly had a stash of cash with him (perhaps $5,000?) and that money was nowhere to be found when his body was retrieved.

Finally, the idea that it might just have been an accident was due to the likelihood that he had been drinking.

sf_20thstreetandbay_googlemap

Potrero Point is close to the foot of 20th Street and the Bay.

At the time I first heard this story, roughly 25 years ago, I decided to just order his death certificate from Sacramento.  And so I did.  But the certificate is equally vague on the reasons leading up to Willie’s death by drowning, stating “whether accident-suicide or murder, jury unable to determine”.

p32-10-vital-williamcolbert-copy

A few years ago, I found the coroner’s report online at FamilySearch.org.[15]  It’s not significantly different from the death certificate.  Willie’s brother John was an informant in both cases.  Willie’s car was missing, and while members of the family thought he might have driven overboard into the Bay, the car was later found to be at the intersection of Mason and O’Farrell Streets.

masonandofarrellstreets_googlemap

William was buried at Holy Cross Cemetery, in Colma, California.[16]  I cited the Find A Grave memorial, but I’m the one who created and maintains that memorial, so I am citing myself!  The photo of the grave is one I took; what I have mislaid is the location of his grave.  The cemetery office will have that information.

Cassius Dempsey: By the crook of a finger – 52 Ancestors in 52 Weeks, # 5

/ cathmary1030 / Leave a comment

The other day I asked my dad if he knew how his parents met.  As a matter of fact, he did, and I’m glad I asked him before it got too late.
Dad told me that he mostly heard the story from his dad… Grandpa (aka Cassius Patrick Dempsey) had gone to one of the local public dance halls, I guess for the Irish neighborhood, and my grandmother was sitting against the wall with some of her friends.

Grandpa noticed her immediately, and there were plenty of men who approached her to dance; she turned down every last one of them.  She laughed and talked with,  her gal pals, but did no dancing.  But Grandpa, from across the room, kept an eye on her, and when, in her laughing and talking, she turned his way and he grinned and crooked his finger at her.

nanaGrandpa

And my grandmother nodded ever so slightly, so Grandpa came over to talk to her.  

So, by the crook of a finger, here we all are: my dad, his siblings, me and my own siblings, and my cousins, and now the next generation.  It’s an odd feeling to realize an entire relationship existed and generations of the Dempsey family exist by the crook of a finger…

 

 

 

 

 

Pictures Really ARE worth a thousand words (or more!)…

/ cathmary1030 / 1 Comment

I’ve been struggling to make sense of — or, more accurately, wisely use — my dad’s matches at Ancestry to extend some of his lines.  Dad has one great-grandparent who was born in the U.S.; the others were all born in Ireland (where all but three remained throughout their lives.)  So, I’ve long thought most of my dad’s matches are not easily assignable to one of his great-grandparents because there is much I don’t know about the aunts/uncles/first cousins of those ancestors.

Now, that may still be the case to some degree, but I did have an eye-opener when I used the NodeXL template with Excel to cluster my matches.  NodeXL is a template for graphing your networks (often in reference to social media)  — see here. I found about the tool from reading Shelley Crawford’s blog Twigs of Yore; she has an entire step-by-step series on how to create visual networks of your Ancestry DNA matches using NodeXL and Excel. (An indexed version is here.)

So, I downloaded my dad’s matches at year-end from Ancestry using DNAGedCom, and loaded the data into the NodeXL template.  I limited the number of matches to those who share at least 17 cM with my dad; I also did not include my brother or me as matches, nor my paternal 1st cousin.

The reason you want to exclude close matches is  because they will match so many people you (or your target person) that there will be connections all over the graph, and you won’t be able to discern any useful information.

For this same reason, I also excluded children and grandchildren of matches, for those cases I know about.  (As a disclaimer, just to be clear, with Ancestry’s matches, I have no way of telling if match A and match B are, say, child/parent to each other — unless I personally know A and B, or unless I’ve “met” online regarding our shared matches, and they’ve shared that with me.)

That’s the context; here is the first picture of Dad’s top 1,000 (or so) matches clustered into the top groups.

dad_ancestrymatch_clustering_majorgroups

The bigger dots represent the closest genetic connections to my dad.   Big dots exist in the navy dot group (upper left), the turquoise group (lower left) and the kelly green group (upper right).

The grey lines denote connections, both within groups and between groups.  In one easy glance, one can determine that the group most tightly related to each other is the group on the top row with dark green dots.  It looks like a web.

As far as inter-group connections go, the turquoise dot group seems to have the most connections with other groups.

So, when I highlight the turquoise group, what do I find?  Connections to most every group of matches my dad has — except for the navy blue group.   Which is kinda cool — but so what?  Unless you know something about the matches within the group.

So, the matches in the highlighted group above are all kin to my dad’s great-grandfather, Archibald Lamburth (born c. 1833 Tennessee – died 1909 San Francisco).  He has the distinction of being my dad’s only great-grandparent born in the United States.  Given that the bulk of Ancestry’s DNA customers are U.S.-born, and that many with colonial ancestry say they have many thousands of matches, I suspect most of these connections will tie back to 18th-century U.S. and the colonies should I ever break this “brick wall”.

My second surprise was looking at the navy blue group.  Other than the one outlier I have yet to explore, all the matches are intra-group matches.  This group includes known close relatives of my dad’s maternal side.

dad_ancestry_match_nanacluster_all her lines

My dad has matches to his maternal grandfather‘s side (and his parents AND grandparents), as well as to his maternal grandmother‘s side (and her parents), the clustering algorithm does not distinguish between the two lines — at least based on the current population of matches used.

I may need to do a separate analysis on these particular matches — perhaps bringing down the filter to 15 cM — to see if I can break out that group into Maternal Grandfather and Maternal Grandmother.

Right now, the only useful information is that my dad’s mother’s matches and my dad’s father’s matches are separate.  They weren’t related to each other, based on the information we currently have — the above graphs, plus the genealogy I’ve already done.

The next picture, below, shows how some close genetic relatives (> 275 cM shared, in this case 1st cousins 1 generation removed), share matches with other groups.  This cluster could be a Dempsey cluster, with ties to Lamburth kin.  Which makes sense in my family tree since a Dempsey married a Lamburth.

Notice also that the group is somewhat open, like a child’s scribble.  Not everyone within the group is closely connected to everyone else in the group.

An example of a tightly-connected group is below. This is the group with dots in chartreuse green. Right now, I have no idea how they fit into the family tree.  It’s pretty much a self-contained group, with minor ties to the Lamburth (dad’s paternal grandmother’s side) group, but nothing significant.   Yet.

That was a look at my dad’s clustered Ancestry matches; sometime in the near future, I’ll take a look at my mom’s clustered Ancestry matches using the NodeXL tool.

 

Margaret Colbert Dempsey: 52 Ancestors in 52 Weeks, #4

/ cathmary1030 / Leave a comment

Nearly 5 years ago, Amy Johnson Crow came up with the idea of writing about a different ancestor each week (hence “52 Ancestors in 52 Weeks” — see here and here.) The premise was to put together a story in words, images or videos (or some combination) about a different ancestor, so the stories you had about your family were captured.  And if you were a hard-core researcher, so much the better — it was a way to organize the “stuff” you had gathered about a family member and get it into a coherent format, perhaps even seeing where you might lack info.

Which brings me to this “52 Ancestors” post.  I realized as I wrote up this summary about my paternal grandmother that I actually know very little about her!  I saw her only a few times in my life, first of all, and most of what I know about her is either from records (census, vitals) I discovered or stories my dad told me.  And then I have to balance that with the fact that all of her children and grandchildren are still alive… how much is “too much” for a blog post?

So, what do I know of my paternal grandmother’s life?  

Her name was Margaret Aileen Colbert and she not only lived her entire life in San Francisco, California, but she lived her entire life in the same house, just off Army Street (now known as Cesar Chavez Street).  She was the third of 4 children born to William Cornelius Colbert and Ellen (aka Eileen) Houlihan, both formerly of Athea, Co. Limerick, Ireland.

Margaret was born on 19 January 1908; the name on her birth certificate is given as Eileen.[1]  She had two older sisters: Honora Marie, born in May 1902 in San Francisco, and Anita, born in September 1903 in San Francisco.  Margaret’s younger brother William C. Colbert (aka “Babe”) was born in June 1910.

Margaret was just shy of 4 years old when her mother, Ellen (Houlihan) Colbert, died in San Francisco on 15 December 1911, of peritonitis due to a miscarriage.  Her father eventually remarried, circa 1922, to a woman named Harriet Maley, and in August 1923, Margaret’s half-sister Cornelia was born.

Margaret’s father died in October 1931, when Margaret was 23 years old.  Then, 18 months later, she married Cassius Patrick Dempsey.  I do not know how they met.  They married in Hollister, San Benito County, California – and I do not know why they married there instead of their hometown of San Francisco.

Throughout their marriage they lived in the house that my grandmother’s Uncle Jack Colbert built, which was also the house she grew up in.  My father was their eldest child, of three children.  A sister followed 6 years later, and a brother 11 years after that.  All of them grew up in the same house too.

Me with my grandparents, 1962

I was 8 months old when my parents and I moved to Florida from California; we lived in Florida for 5 years, where my siblings were born.  Then we moved to the D/FW area.  My grandparents came out to Florida for Christmas in 1963, when I was a toddler.  That was the only time we ever saw them for Christmas, not that I remember it!  We do have home movies, and photographs, however.

As for times I remember seeing my grandmother, I can count them on one hand, as we rarely made the long trip out to San Francisco, and they never visited us in Texas. 

The last time I ever saw my grandmother was when I visited my aunt (who is also my godmother) in San Jose over the Bicentennial Fourth of July.  My aunt and uncle were away for a short business trip, and my grandparents came down from San Francisco to stay with me and my younger cousins.

My grandmother died of heart failure on 30 October 1983, at the age of 75, when I was 22 years old.  She was buried at Holy Cross Cemetery in Colma, California.
