In my previous Blog, I looked at creating genealogical trees using proposed Crann DNA matches. The matches I looked at were primarily at AncestryDNA. The advantage of Ancestry is that if the matches have trees, they are easy to find. Since that Blog, I had a question from Molly in my Newfoundland Dicks DNA Study Group. Molly would like to know if the DNA shows that she is descended from the Cranns. Molly has two lines of Dicks ancestry. One of them leads back to an early Crann connection.
Molly (or Marilyn) and her brother Howie are on a Dicks/Crann line on the right. They are also on a Dicks/Joyce line. My wife’s mom Joan and Joan’s half Aunt Esther are on another Dicks line. In my previous two Blogs, I got around a lot of the non-Crann common ancestors by finding a Crann descendant who moved from England to New Zealand. This tended to isolate matches to just Cranns and made things simpler. In the chart above, a lot of these people are related to each other in multiple ways due to living in isolated areas. Also Joan, Marilyn, Howie and Forrest did not test at AncestryDNA. Fortunately, they are all at Gedmatch.
Here was the match list at AncestryDNA:
These were presumed to have Crann ancestors. I know that Esther, Heather and Ninky are listed at Gedmatch. There are also others.
People Who Match One or Both of Two Kits
Getmatch has a utility where you put in two matching people and others show up that match both those people. This is sort of what AncestryDNA does with their matching feature. I did that for Esther and Heather. From that list, I found some people that match Heather and also match Esther.
Wayne and Marjorie
Wayne and Marjorie show up first on this list. Marjorie is probably the M.R. listed at AncestryDNA with the large tree. Wayne and Marjorie are siblings. If I’m interpreting Marjorie’s tree correctly, I get this:
This adds another New Zealand line in green to compare with the Newfoundlers. Also on that list of common matches are my mother in law, Joan and Molly who asked about her Crann connections. Forrest, who was listed as a Crann/Dicks descendant was not an obvious match to the New Zealand DNA testers. However, she did show a tree match to John Crann. Based on that, I’ll add Forrest, Molly and Howie:
Forrest also had that John Crann’s wife was Elizabeth, so I added that in. Under this tree, it would not be surprising for Forrest to not have a DNA match as Forrest and Heather would be 4th cousins twice removed. Next, I’ll add my mother in law and her half Aunt Esther:
Note that I just corrected Wayne and Marjorie and moved them up one step after getting in touch with Marjorie’s daughter Donna. In all subsequent diagrams, they should be shown as here.
My next step is to take all the tested people in the Tree above and compare their DNA in a spreadsheet, to look for Triangulation Groups (TGs).
Chromosome 10 TG
Here Heather, Wayne, Marjorie, Molly and Howie match each other. Joan and Esther match each other but not the rest of the group, so they are not in the same TG.
Based on the above, this appears to show a common ancestor of Crann for Marilyn. It’s a little surprising as Marilyn and Howie are 6th cousins to Wayne and Marjorie.
TG11: Heather, Esther, and Joan
I suppose Esther and Joan do not want to miss out on this TG which seems to point to Crann in Netherbury, Dorset, England:
This shows that the DNA that Joan and Esther match with Heather got to them somehow. That path had to be through the Upshall or Dicks wife (or both).
TG22: Esther, Heather, Wayne and Marjorie
Here, the match between Marjorie and Wayne are not highlighted as siblings are usually counted as one person in a TG.
It is interesting that after 250 years, the DNA still points to the Dorset, England home of the Cranns via Newfoundland and New Zealand.
These were only a few TGs. I only picked the DNA matches where there were pretty good New Zealand trees. There are probably other New Zealand DNA tested people that triangulate with Newfoundlanders who descend from the Crann family of Dorset.
If Heather wanted to map her Crann DNA based on these four testers, it would look like this:
