Genetic Distance of 9 How likely we are related?

[Jim Barrett]

Hi there,

Are we related somehow in the last millenium, or are we related somewhere long ago before?

Romain,

The answer depends on two things. 1) What is your Haplogroup? and 2) What is your Haplotype? If you have a rare Haplotype, even in a common Haplogroup the chances may be good. If you have a common Haplotype and Haplogroup, say R1b1 or a subclade of it the odds are against it.

You and the other person need to have more than 25 markers. Go to your myFTDNA website and look at you 25 marker matches. If there is a number after this person's name that is the number of markers he has had reported. The number could go up in the next week or so if he is a new customer and has ordered more markers. If there isn't a number after his name he has only had 25 markers reported so far.

What about your other matches? Do you have any? How many markers have you ordered? What is you Haplogroup? Have you loaded you data to Ysearch? If so what is your ID? Are you in a project? If so, does the project have a website and how do we find you in that website?

What it boils down to is we need a lot more information before being able to give you an informed answer.

Re haplogroup, he says he's tested as SRY2627 (aka M167) so I believe that would make him R1b1b2a1b3 by FTDNA's current tree or R1b1b2a1a2c according to the ISOGG 2010 haplotree.

Ok, the rest of the markers came back today. So here is the scoop. He matches on 36/37 markers to a man with a totally different surname. The only matches to ppl of the same surname are at a distance of 9 or higher, which I assume basically rules them out. He is also a match at 34/37 to several men of a diff surname (mainly the Fancher men , all from the same line going back) so I assume this means he did indeed have an NPE and any idea on what generation I should be looking at for this to have occured?

It's not necessarily an NPE. Depending on the TMRCA between the haplotypes, and the history of surname adoption in Ireland, it's possible that you've discovered the link between two branches of the same family who simply adopted different surnames.

24 out of 25 markers: are we related ?

Hi and thanks for replying,

I have been tested SRY2627 (aka M167) BY GENEBASE and ordered a 67 marker DNA test from FTDNA. So far I received 37 out of the 67.
Please, find my markers (Romain Grouazel Krauss) compared on YDEARCH with the other person (Borders):

NK38M GROUAZEL KRAUSS Saint Malo (1479) dit du Vivier sur Mer (35) BRITTANY, France 13 25 14 10 11 14 12 12 12 13 14 29 17 9 10 11 11 25 15 19 29 15 15 17 17 11 11 19 24 15 15 18 17 37 37 12 12

UPZX2 Borders America 13 25 14 10 11 14 12 12 12 13 14 29 17 9 9 11 11 25 15 19 29 15 15 17 17

We differ on DYS459b by one point. I have DYS459b=10 he has DYS459b=9

Thanks for your help
