More Dicks (and Joyce) DNA from Newfoundland

Thanks to the Newfoundland Gedmatch Facebook Group I recently ‘met’ a new Dicks descendant who had DNA tested. Trudy is from the Joyce Line of Dicks like many other in the Dicks DNA Project.

Trudy is in the bottom row of green DNA tested Dicks descendants. She is 7 generations away from Christopher Dicks b. about 1784. This is the main Dicks Line that I have been looking at. However Christopher had a brother of interest also named Henry.

Seven generations is a long way away for autosomal DNA, but we will see what Trudy’s DNA shows us. As alluded to in the Blog Title, Trudy also has Joyce ancestry.

On a certain day in the early 1800’s Rachel Dicks married James Joyce. They had at least seven descendants that had their DNA tested. And of course they had many descendants that didn’t have their DNA tested. Trudy’s closest relative in the chart above is Pauline. They are 1st cousins once removed.

Here is how Trudy matches the other Dicks descendants with tested DNA:

That is a bit small, isn’t it? This shows no matches to the Henry Dicks Line, so we won’t need to look at them in this Blog. We can stick to the descendants of Christopher Dicks b. 1784.

Triangulation Groups

I tend to focus on Triangulation Groups (TGs). These are groups of people that match each other on the same segment. When this happens, it is a sure bet that the people in the TG have a common ancestor. There should be potentially two types of TGs that Trudy would be in: new ones and existing ones. The existing ones may tell us something, but the new ones should be more interesting. In addition, there is the possibility that Trudy could be in a Joyce TG, a Dicks TG, or even one from a different surname.

Downloaded segments

First, I download the matches of all the Christopher Dicks descendants and compare them. So I’m not re-creating the wheel, I’ll reproduce my TG Summary from a past Blog:

The first interesting thing I see in my downloaded segments is here at the end of Chromosome 1:

Trudy is in a TG with Esther and Forrest. Esther is my wife’s 1/2 great Aunt. Note that Judy and Wallace are not in this TG. They have plenty of other places to have their DNA match as they are niece and uncle.

As far as I know, Esther, Trudy and Forrest all share the DNA from Christopher Dicks and his wife Margaret, so that is what it looks like this shared segment is (unless anyone else knows of a different shared ancestor in each of their ancestry).

The next interesting TG in chromosome 4

Here I see Nelson, Molly and Trudy in a TG. This TG will be a little more challenging. Howie would also likely be in the TG if we were to lower the limits. One of the challenging things about this TG is that Molly descends from two Dicks Lines:

Nelson is from the Adams Line. Trudy is from the Joyce Line. Molly is from the Joyce and Cran Line. Nelson is Trudy’s 3rd cousin, three times removed. Nelson is Molly’s 3rd cousin, twice removed. Molly is Trudy’s 4th cousin once removed and 5th cousin, once removed. My guess is that Molly is related on the Joyce line as that would be closer to Trudy, but there is no way to know with certainty.

Moving right along.

Chromosome 5 TG – The Joyce family

Here I believe I see a Joyce TG:

Pauline, Molly and Trudy all descend from the Joyce Line. Within that TG is another TG with Wallace, Joan and Esther. I had to take the match between Wallace and Esther down to find it, but it was there. Then again, we see the close Judy/Wallace relationship. They could match with Lewis DNA, for example.

Untangling Chromosome 15

Here is a TG with Trudy, Esther and Howie (Molly). Think of Howie and Molly as a tag team. As siblings, their DNA can be interchanged in many situations. Here we are missing a match between Esther and Molly. However, it would have to be there at a lower threshold.

There is a lot of mystery in this TG. I assume that the TG is Dicks. However, Molly and Howie are from 2 Dicks Lines and Esther has Dicks on her father and mother’s sides. On Esther’s mother’s side, I don’t know where her Dicks ancestors come from.

Here, the only unambiguous line (as far as I know) is between Trudy and Christopher Dicks by way of the Joyce Line. For Esther, Marilyn and Howie I am not as sure. Sandra and Cheryl listed above are both from the Adams Line of Dicks, so that is a likely source of shared DNA for those two.

TG Summary

This chart is getting large:

Trudy is in 5 TGs. I think that 4 of them are new. Two of them appear to be Joyce TGs and three Dicks TGs.
