DNA Support for My Children’s Warren Ancestry

In some of my previous Blogs on my children’s ancestry, I have noted a discrepancy. It appears that one of their grandparents who was a Cavanaugh should actually be a Warren. I mention how I came to that conclusion in this Blog and elsewhere. In that Blog, I gave strong evidence that Heather and JJ’s grandmother’s father John Edward Cavanaugh was actually a Warren. Although I had strong evidence for that, I was missing some evidence, including DNA correlation. That is, until recently.

Heather’s DNA and Genealogy Match with Eileen

Here is Heather’s match with Eileen:

In addition, Ancestry suggests this Warren connection:

These are ThruLines. Ancestry suggests evaluating the ThruLines. Here is Eileen’s tree on her maternal side:

Eileen has back to Blanche Sullivan. I have Bridget Warren who married John Sullivan in 1855 in Lowell:

That means that I just have to make the connection. Here is Bridget in 1880 with her family including Francis:

Ancestry transcribed Bridget as Pridy for some reason.

Francis or Frank J Sullivan

Here is Frank in 1900 in Lowell with Daughter Blanche:

This appears to be the birth record for Blanche from 1889 in Lowell:

And, to tie it all together, here is the marriage record for Francis Sullivan:

Any Other DNA Matches for Heather?

I checked to see if Heather had any shared matches with Eileen and I didn’t see any. I did see this more distant DNA match that Heather had with Robin:

I’ll need to star that as Ancestry plans to take away the smaller matches under 8 cM. Here is how Ancestry shows the connection:

That means that Robin and Eileen must be 2nd cousins. Ancestry wants me to evaluate, but I think that Robin likely knows who his mother is. Here is a bonus with Heather and Robin’s shared DNA matches:

This shows that Heather’s brother JJ matches Robin at a higher level. JJ may also match Eileen at a level under 20 cM.

JJ’s Warren DNA Matches at Ancestry

Here is JJ’s DNA match with Robin:

When I look at Robin’s tree it only shows his mother and father. However, I think that Anestry has it right:

This shows that Mary H Dwyer and Mariam Hazel Sullivan were born on the same day.

Here is the family in Lowell in 1930:

Mary Hazel’s daughter Mary Jaqueline apparently went by Jaqueline. That seems to make the connection in Robin’s tree.

JJ and Eileen

Here is JJ’s smaller match with Eileen:

This match is over 8 cM so is not in danger of being stripped away by Ancestry.

JJ’s Shared Match with Eileen and Robin

I’ll just call him N. Here is N’s maternal tree:

N is on the Dwyer Line, so he is more closely related to Robin. I’m not sure why Ancestry didn’t pick up N as having a shared ancestor with JJ. Perhaps one will come up eventually.

Putting It Together

Here is how all the DNA matches fit together:

N is 2nd cousin once removed to Eileen and Robin and 4th cousin once removed to Heather and JJ. The confusing part from what I can tell, is that Louisa Gatley was actually Louisa Cavanaugh at the time she had John Edward Cavanaugh. She was a widow and John J Warren was a widower at the time. John J died not too long after John Edward was born in an accidental drowning.

Summary and Conclusion

  • The match between Heather and Eileen was a good find as it provided additional evidence that John J Warren was the father of John Edward Cavanaugh.
  • That means that even though Heather and and JJ’s maternal grandmother was Agnes Cavanaugh, they don’t really carry any Cavanaugh DNA. That is because John Edward’s mother was only a Cavanaugh by marriage and his father was John J Warren.
  • Heather, JJ, Eileen, Robin and N form a genetic cluster which gives further evidence that the tree is correct.

Post Script

In my previous Blog, I noted that perhaps a baptismal record would show up for John Edward Warren/Cavanaugh. Here is the record from St. Peter, Lowell in August 1880:

Here is the Ancestry transcription:
