A New AncestryDNA Match with McMaster and Frazer Ancestry and My Sister Lori’s Shared Clusters

I was checking my new matches at AncestryDNA and came upon a match named Rebecca who has a Frazer ancestor from Sligo. This got me interested.

Rebecca’s Frazer Genealogy

Rebecca has a small tree. Here is Rebecca’s maternal side:

I sent a message off to Rebecca, but I’ll also try to build out her tree. It seems like this James may be the James Robert Frazer I have in my tree:

The death date is close.

My guess is that here is how I am related to Rebecca:

That makes us third cousins. She is also the first DNA match that I know of from the William Frazer Line. I did hear back from Rebecca who confirmed that James Robert Frazer was her grandfather.

My DNA Match with Rebecca

Rebecca and I match at 64 cM over 6 segments. Rebecca shows on my list as a 4th cousin, however, the AncestryDNA table for a match of 64 cM shows this:

We have a 37% chance of being third cousins and a 4% chance of being fourth cousins. Rebecca and I don’t share Whitney as a DNA match. Whitney also tested at AncestryDNA:

It gets complicated because Rebecca’s grandmother was also a McMaster. Here is Rebecca’s grandmother’s McMaster side:

I also descend from James and Fanny McMaster. Here is another way to show this:

 

This shows that Rebecca is Keith’s 1st cousin once removed. Also Rebecca is both my third cousin as well as my fourth cousin. This shows how Rebecca would be related to me on my McMaster side. Rebecca descends from Margaret and Hubert McMaster who were the children of Fanny and James McMaster. The people in green have uploaded their DNA results to Gedmatch.com. If Rebecca did this, I should be able to tease out the Frazer DNA from the McMaster DNA. A further complication is that Fanny McMaster who is at the top of the tree is the daughter of Margaret Frazer. However, this Margaret Frazer is from a different Frazer line than George Frazer who is in the tree.

Shared Matches With Rebecca

Here are my shared DNA matches with Rebecca in addition to the shared matches of my siblings and Rebecca at AncestryDNA:

I have information on how I match BV:

BV is a third cousin, twice removed to me, my siblings and Rebecca. This seems to indicate that the DNA connection is on the McMaster side.

Lori and Marshall

In doing the shared matches, with Rebecca, Lori and Rebecca have a shared match with Marshall:

Here is what Marshall has about George McMaster – his 2nd great-grandfather:

It would be nice if I could fit George into the William McMaster/Margaret Frazer Tree above. Margaret Frazer moved to Ontario with most of her children. The best way I know to review Marshall’s tree is to create my own Marshall Tree.

Here is Frederick McMaster with his family in 1911:

Father George was a farmer and Frederick Herbert appeared to be a young twin.

1871 Census

Here is Abraham McMaster and probably his father George in the 1871 Census:

1861 Census

I am finding the 1861 Census difficult to interpret:

There is a note by Abraham which appears to say married. These appear to be the same people as in the 1871 Census. However, the last name is spelled McMastrin. Also Jane shows an “m” for married but also appears to be only 10 years old! I assume that this is the same Jane who shows as 27 in the 1871 Census. A little squiggle in the 10 could be interpreted above as an 18. Here, at least George and Catherine are the same age.

1851 Census

The 1851 Census is stranger still:

Here are 5 McMasters and the oldest is 12. Did the family leave them temporarily? I assume that this is the same family, but I am not sure. If this is correct, and two year old James McMaster was born in Ireland, then that means that they must have moved to Canada around 1850.

The assumption is that Abraham was born about 1837. This seem born out by this grave marker from St. Mary’s Anglican Cemetery in Osprey, Ontario:

Getting from Abraham Back to George McMaster

If Abraham was born in Kilmactranny Parish, that would have been during the time when records were missing. Here is one George shown in the Kilmactranny records:

William son of George and Jane McMaster

Born                                      Bapt. Aug 18, 1843

However, the timeframe is off for the William above unless he was born a while before he was baptized.

Here is where Osprey or Ospry is:

Another George McMaster?

I mentioned another George McMaster in this Blog. This George was married to a Jane and had a son named George Arthur McMaster:

This George was in Vaughan as early as 1847 when his son George Arthur was born:

Vaughan is in York County a little above Toronto.

The question is, was this George, the same as the father of Abraham above? Or put another way, did this George and Jane McMaster have a son named Abraham? The George from my previous Blog married Jane McMaster. The Jane above is believed to be Jane McMaster who is a sister of my ancestor.

Just to confuse things further, Ancestry gives this hint for the George in my Tree:

That hint was based on this tree:

I put a box around my ancestors.

Any Conclusions?

From the above, I would say that the George McMaster who married Jane McMaster is most likely not the same as the George McMaster listed above in the 1861 Census along-side of Abraham McMaster. Two trees at Ancestry have the George who married Jane McMaster dying in 1847. This is likely right as Jane marries William Thompson in 1851.

The fact that Abraham was living in the same or next house as George McMaster in 1861, implies but does not prove that George was the father of Abraham:

My further guess based on the genealogy and DNA is that the shared match between Lori, Rebecca and Marshall goes back further into McMaster history. I have been unable to connect all the McMasters, but the DNA seems to be pointing in the direction of that connection.

More DNA

It seems I have made this simple match with Rebecca into a complicated Blog. That is because Rebecca’s DNA match with my family seems to point to the McMaster side of my genealogy which is a bit convoluted – not unlike the Frazer side.

Here is some more detail on Rebecca’s shared DNA matches with my family:

 

Here I have added my match numbers with Rebecca as well as my siblings’ match numbers. I have also add match numbers where they appear with shared matches. In scanning from left to right, it appears that Lori has the most shared matches. After that, I added whether the match had an Ancestry Tree. CA means that they have a tree and Ancestry indicates that we share a common ancestor. I share common ancestors with Rebecca, but either Ancestry hasn’t picked up on that yet or Rebecca’s tree is not detailed enough. There are few directions I could take at this point. I could look at more trees or at more DNA. I’ll try the DNA route.

My Sister Lori’s Shared Clusters

Jonathan Brecher has a utility called Shared Clustering. I’ll run Lori through that program as she has the most shared DNA matches with Rebecca. Here is how the Lori’s shared clusters look at a limit of 40 cM:

At that level, Lori has 4 clusters. Cluster 1 represents her paternal grandfather side. Cluster 2 represents Lori’s maternal side and Clusters 3 and 4 on Lori’s paternal grandmother’s side. Rebecca’s match is right in the middle of Cluster 3. Right above Cluster 3 is a match with Michael. He and Lori have a Frazer common ancestor, but because Cluster 3 appears to be a McMaster Cluster, Michael is not in Cluster 3.

I have circled the different Clusters in green.

Whitney also shows up in Lori’s Cluster 3:

Melanie, Emily and Paul don’t show up because they had their DNA tested at different companies. Melanie doesn’t show up on Lori’s shared match list with Rebecca. However, because both Rebecca and Melanie match other who are in the Cluster, they are included in Cluster 3.

Bringing Lori’s Shared Clusters Down to 30 cM

I’ll try Lori at 30 cM to see who we pick up along the way. At this point, I’m just interested in the Cluster Rebecca ends up in:

Now Rebecca is in Cluster 1. A new Cluster for Frazers has appeared in Cluster 2. A few matches who were previously in Rebecca’s cluster jumped ship to the new Cluster 2 at this level. The last two members of Cluster 1 appear to be fairly closely related to Cluster 2.

Here is a summary of Lori’s clusters so far:

Bringing Lori’s Shared Clusters Down to 25 cM

At this point, Lori has gone from 9 clusters to 19:

Rebecca is now in Cluster 9 with a Frazer Cluster 10 right below.

Bringing Lori’s Shared Clusters Down to 20 cM

At this level, I should see Marshall. I had looked at his Irish/Canadian McMaster ancestry earlier.

Believe it or not, I find this cluster detail very interesting.

Clusters 27 – 33

Here is my markup:

There is a connection between the two pink squares. These represent Lori’s Frazer ancestry.

It appears that Violet Frazer and James Frazer were first cousins. The second pink chart above Represents Richard Frazer and his daughter Violet. That leaves the first pink box in the Shared Cluster Chart which should represent the James Frazer side.

However, notice that the second pink square is split into two. A possible explanation is that one of the two clusters could represent the unknown spouse of Richard Frazer born about 1777. I would assume that Cluster 30 could represent Richard’s unknown spouse. Whitney is in this cluster, so I am proposing that Whitney may have gotten more of the DNA from Richard Frazer’s wife:

It’s a theory.

A Clue to Marshall’s Ancestry?

Marshall is in Cluster 29 which subtly separated from Cluster 28. However, notice that Cluster 28 has more matches with other clusters. Cluster 29 has fewer matches. That leads me to believe that Marshall’s genealogy goes back on the James McMaster Line.

This leads me to another observation. That is that Cluster 29 appears to match up better with Cluster 33:

I had that Clusters 32 and 33 probably represent William McMaster and Margaret Frazer. So that tells me that William McMaster could be represented by Cluster 33.

Lori’s Final Shared Clustering

Lori’s final shared clustering should look the same as the 20 cM clusters. The difference is that small matches are added in down to 6 cM. My understanding is that these matches will generally be outside the clusters but associated with the clusters. Let’s take a look:

Here is the detail for Rebecca and Marshall. They are now in Cluster 40 and 41. In the past two runs Lori had 46 clusters. However, in this final run, the clusters got shuffled around – I suppose due to the smaller matches being added in.

Well, I could keep on going, but I’ve gone on too long already.

Summary and Conclusions

  • I was happy to find a DNA match with Rebecca. We are third cousins through our common ancestors of George William Frazer and Margaret McMaster.
  • Based on the DNA, Rebecca and I are more related on the McMaster side. That is not a surprise as our common ancestor Margaret McMaster had two McMaster parents and Rebecca’s grandmother is also a McMaster.
  • I also looked at some more distant DNA matches going back William McMaster born about 1790 and his wife Margaret Frazer. They left for Ontario in the 1800’s with their children but left one daughter Fanny stayed behind in Kilmactranny Parish, County Sligo, Ireland.
  • I then did a somewhat complicated cluster analysis focusing in on my sister Lori, her match with Rebecca and their common matches.
