Hi Belinda, slightly off topic but related to distant cousins, I saw your name pop up in my email stream, just as i was placing a Belinda and Nicholas Dettman into my GenomeMate Pro database. You match 4 of my kits, on my mothers side?, 16 cMs on Chr4. (Gedmatch T203846) Must be back a fair way. Another name from my Gedmatch list just happened to turn up posting on the FTDNA facebook page yesterday. Such serendipity!! cheers (cousin) Marcus Strudwicke -----Original Message----- From: Belinda Dettmann Sent: Saturday, September 16, 2017 7:55 AM To: [email protected] Subject: Re: [DNA] I don't match my 4th cousin It is very common not to match a fourth cousin as the chances of not matching are more than 50%. You do need more cousins to test and it can be illuminating to get more of your own relatives tested as well. Then compare everyone with everyone else and you will often find a family relationship showing up with a particular group. Also, try dropping the criterion on gedmatch to 5/500 and retesting all the comparisons you can.

I don't know how likely this is but I think it could happen. I've looked for gedmatch segments down to 3CM with no matches. Then I tested a second cousin of Dorothy's, Bart, who matched Dorothy appropriately. All eight of us are on Gedmatch. The Dorothy group of two doesn't match any of the 6 in my group. Bummer. However, Bart is a 7 CM match on chromosome 12 with a sister and me on 23andme. 13 CM is the average amount that 4th cousins would share and the range is from zero to quite a bit. I'm not overly surprised that a small match on 23andme disappears when transferred to gedmatch but it complicates my testing. So, how likely is it that the two groups are related or not related? I'm sure the answer is to find more cousins to test. I have no 2nd cousins on this line. I talked to a 3rd cousin on this line that wouldn't take a DNA test:( Any thoughts and recommendations appreciated before I break the news to Bart & Dorothy.
