<\/a><\/p>\nHere is a slightly bigger picture:<\/p>\n
Fortunately, Jane gave me access to her matches and I found Caz as one of Jane’s Shared Ancestry Hints. I’ll add Caz to the Australian Line of Frazers:<\/p>\n <\/p>\n This is becoming a good group.<\/p>\n Here is Caz in what I call the Stinson Group:<\/p>\n The furthest out relationship on this branch is 5th cousin. Here are some guidelines for the chances of matching a specific cousin.<\/p>\n Here is what I get for the DNA for the above group:<\/p>\n I left out the blue line as I am not as sure about them. The matrix shows how everyone matches everyone else in the group. It is a little complicated as some of the Frazers intermarried and some of these people are matching Frazers outside this specific group. Note that everyone matches each other within the Archibald Stinson\/Catherine Parker Group. Everyone in that group is a third cousin once removed or closer.<\/p>\n Triangulation is when three people match each other on the same segment of the chromosome. Here is one example:<\/p>\n Here Caz matches Michael and Jane. For these segments to triangulate, Michael also has to match Jane which he does. Notice that Michael also matches Vivien. Vivien would be in the Triangulation Group (TG) also, but Vivien probably matches Caz below the match threshold of 7 cM.<\/p>\n Here is how I would show the TG on a tree:<\/p>\n This should be important information for Jane and Michael. That is because Jane and Michael also match on the Richard Frazer Line.<\/p>\n Although it is possible that the DNA is from the Richard Frazer Line, it is much more likely to be from the Frazer\/Stinson Line. That is because a match between Caz and Jane or Michael would be an extra generation away.<\/p>\n This TG is less ambiguous:<\/p>\n Caz, Don and Cathy are not known to be descended from other Frazer Lines.<\/p>\n When people are in a TG, they\u00a0share a common ancestor.<\/p>\n For example these three may be sharing the DNA from either John Parker Frazer or Honora White. However, their children were Frazers, so we consider the DNA to be Frazer DNA.<\/p>\n This TG is similar to the second one I looked at:<\/p>\n In this case, Vivien replaced Don in the TG. These four TGs represent DNA from ancestors from three different generations of Frazers – from 1778 to 1827.<\/p>\n Here I will do a little fishing expedition to see who Caz matches and who she doesn’t. Here is what I get:<\/p>\n This brings up some interesting possibilities and may make me revise what I wrote above. First, let’s look at Charlene. She is on the McPartland Line. I have written many Blogs about this family. This is a small match that Caz has with Charlene, so it may or may not be valid.<\/p>\n The more interesting match is on Chromosome 1. Here there are two possibilities. One is that Paul, my family (Heidi, Lori, James and Jon) and Emily all have McMaster ancestry. So the TG could be on that family. Another is that this is part of an older Frazer TG.<\/p>\n Here is what the TG with the older Frazers would look like:<\/p>\n Note that my blue family is also part of the Richard Frazer group. Michael and Jane are in the Richard and Stinson group. I circled Vivien because she matches some of these people but not all. I think that she would be in this TG if I lowered her match threshold levels. Probably what is happening is that Emily, Paul and my family are triangulating with each other from George Frazer. This in turn was probably DNA from George’s mother Violet who was the daughter of Richard Frazer born about 1761 (on this chart but 1777 on the other chart). The blue circled people then match Jane and Michael as part of the Richard line also. Then Caz matches everyone else through Archibald Frazer and Mary Lilly. This DNA would have come down to Caz by way of Archibald Frazer and Ann Stinson. That means that this is a multiple level TG and a rolling TG. What I mean by rolling is that others come into it at different parts of Chromosome 1.<\/p>\n Seeing as so many people triangulate at the right side of Chromosome 1, let’s take a closer look. Here is an old list of matches tha I have been tracking:<\/p>\n PF is my cousin Paul. MFA is Michael. MB is Mike. I don’t know who he is, but he is in the TG and is likely related. BR is Bill who is related to Gladys. LH, HHM and Jon are my siblings. VO is Vivien. At the time, the common ancestor seemed to be Richard Frazer, now with Caz in the mix, that seems to have changed.<\/p>\n I stared at the numbers for quite a while. I’ll go through the matches. They seem to sort into pre and post-Caz TGs. This will be a little in-depth, so I apologize in advance. I’ll take a tour of Chromosome 1 starting at about position 181 M. My cousin Paul is matching with Jonathan from England on some other line than the TG that Gladys, Jon (my brother), Jim and Doreen are in. I called this TG the Pre-Caz TG:<\/p>\n <\/p>\n This is a fairly recent TG as it represents Frazers born in the early 1800’s:<\/p>\n Paul breaks away from the Jonathan from England and joins the Caz TG around position 202M.<\/p>\n The Caz TG is a large one consisting of ten people. I took out some of the matches as gedmatch doubles the matches and ten people all matching each other is a lot of matches. Vivien drops out of this TG at 203M. Paul joins in at 202M. My family joins in at 205M and Emily joins at 209M. This could be considered two TGs or what is called a rolling TG with people exiting and entering.<\/p>\n I originally had the Caz TG starting later, but Caz does match Vivien on Chromosome 1 if I lower the threshold:<\/p>\n <\/p>\n Here is the much older Caz TG:<\/p>\n <\/p>\n This is a more detailed description of the TG I discussed earlier in the Blog.<\/p>\n In the Post-Caz TG, Caz and Emily drop out and Bill joins the group:<\/p>\n However, Michael and Jane are still in the group, so that makes this Post-Caz TG a Richard Frazer TG. Here are some of Michael’s matches:<\/p>\n <\/p>\n I went back and did a more detailed analysis. Caz dropped out of the above TG but dropped into another one.<\/p>\n Here she is with Don and Cathy:<\/p>\n My normal guess would be that they share Parker DNA because they are overlapping another Frazer TG.<\/p>\n<\/a><\/p>\n<\/a><\/p>\nCaz’ DNA<\/h2>\n
