Gaby’s Butler and Kerivan DNA

My wife’s cousin Gaby recently uploaded her AncestryDNA results to gedmatch. That is good news for my Butler and Kerivan research. My wife’s father is a Butler and a Kerivan on his father’s side. However, because he is also half French Canadian on his mother’s side, he gets a lot of French Canadian matches. Those matches make if difficult to find the Irish Butler and Kerivan DNA matches.

Gaby’s Overall DNA Matches at Gedmatch

Here are Gaby’s top DNA matches at Gedmatch:

  • Already, there are a few interesting things. One is that Gaby has some X Chromosome matches with Virginia and Lorraine. Virginia and Lorraine are my wife’s aunts. We will look at that later.
  • The next point is that Gaby shares about the same amount of DNA with my wife Marie as she does with Marie’s Aunt Lorraine. Such is the randomness of DNA inheritance. Gen in the Chart above means generations to a common ancestor. For example, first cousins have 2 generations to their common or shared grandparents. Marie’s ‘Gen’ amount should be 3.0 (on average) to Gaby as those two are second cousins. Aunt Lorraine should be 2.5 from Gaby as they are 1st cousins once removed.

Butler/Kerivan Genealogy

Here is a brief genealogy as it relates to those close relatives DNA tested and uploaded to Gematch:

Those that have DNA tested and are listed at Gedmatch are in dark bold. Marie, John and Gaby are each 2nd cousins to each other. The 5 testers on the left will share French Canadian LeFevre DNA with each other. However, now with Gaby, the left hand side above will share only Butler and Kerivan DNA. Likewise from Gaby’s point of view, her matches take her Melsis ancestors out of the matching.

Kerivan X Chromosome Matches

I mentioned above that Gaby matches Lorraine and Virginia by X Chromosome. My guess is those matches are Kerivan and not Butler matches. Why do I think that? The important thing to note about the X Chromosome is that the son inherits no X Chromosome from the father. However, Lorraine and Virginia inherited an X Chromosome from their father, Edward Butler b. 1904. That Edward inherited no X from his dad, but did inherit X from his mother Lillie Frances Kerivan, born 1874.

Here is Lily Kerivan’s X DNA that is shared between Gaby, Lorraine, and Virginia:

gaby’s additional X Chromosome DNA

But there is more. Gaby gets more X Chromosome DNA than those on the left side of the Butler/Kerivan genealogy chart. Gaby gets some Crowley X Chromosome DNA.

Following up the tree from Gaby, she got X DNA from her mom, who got it from her mom Lily Butler. Lily got her X DNA from her mom and dad Edward Henry Butler. Edward got all of his X Chromosome from his mom Mary Crowley, b. 1838 in St Johns, New Brunswick. So Gaby may have some of  this old X Chromosome DNA. I say she may as we don’t know for sure. Perhaps it dropped out along the way. However, the potential is there.

Finding other Butlers and kerivans

One way to find other matches on the  Butler and Kerivan sides is to run a utility at Gedmatch. The utility is called ‘People who match one or both of 2 kits’. We are interested in those who match both my father in law Richard and Gaby.

If I choose Richard’s kit number first, I’ll get those in common with Gaby that match Richard. If I choose Gaby’s kit number first, I’ll get her matches that are in common with Richard. I’ll choose Richard’s kit number first as I already have a spreadsheet of a lot of his matches. Here are the results:

I left out the kit numbers on the left and the emails on the right. Also on the right is a check box to choose all the matches where they can be compared. The first three columns are for Richard and the second three are for Gaby. When I pick a lot of the check boxes, I can then compare them in a Chromosome browser.

This is an example of one of the Chromosome’s results. #1 on the browser is a Rooney. There are Rooney’s on the Kerivan side, so this is a good sign. #2 is Gaby. It looks like she is related to #3 also. Now I can go to Richard’s match spreadsheet. I can make an educated guess that both these matches are on his Paternal side.

The first entry in blue above is the Rooney person. The second in blue is Gaby. Others in blue are likely related along that Kerivan or likely Rooney line. The blue means a paternal match. Notice that there are a few other matches with known relatives above that are maternal matches in the same area of the Chromosome. I have them in pink for maternal. Knowing if your matches are paternal or maternal is one of the most important things to know about autosomal DNA matching. If you get that wrong, you will be chasing DNA down the wrong road.
