Thanks, Jim. That is exactly what I needed to understand. I appreciate your response and the clarity of it. -----Original Message----- From: autosomal-dna-bounces@rootsweb.com [mailto:autosomal-dna-bounces@rootsweb.com] On Behalf Of Jim Bartlett Sent: Thursday, November 21, 2013 2:12 PM To: autosomal-dna@rootsweb.com Subject: Re: [AUTOSOMAL-DNA] Question based on results Constance, No. There is a roughly 50/50 chance that the Common Ancestor is through either parent of your Match. You know that your daughter's match is through you and your mother, because she has the same segment with you two. You know that your match is through your mother, because you both have the same segment with your Match. The Common Ancestor, however, could be through either of your mother's parents - you just have no clues at this point as to which of your mother's parents passed this segment down. You also have no clues about how your Match got this segment - which of her parents passed this segment down. If you or your mother have any other known relative who also matches on this segment, then that will tell you more information, depending on how you are related to the relative. The same is true with a Match - if he/she has a known relative who also match you on this segment, then that will tell the Match where the Common Ancestor is on his/her ancestry. atDNA lets us match cousins with any path (male/female mix) from the Common Ancestor, but this is a two edged sword... just because you know part of the path on your side, doesn't tell you anything about the path on the Matches side.

I have a situation that I think I understand, but I want to see if I am on the right track if you will indulge me. My granddaugther, my daughter and myself have all been tested at 23andMe and have our results. There is an individual who is predicted as a 3rd to 5th cousin with all of us (but not yet proven genealogically). We all match on chromosome 1. The results show this person's matches to the three of us as follows: 29.3 cM (Genetic distance) 3846 (#SNPS) 27.6 cM (Genetic distance) 3580 (#SNPS) 10.6 cM (Genetic distance) 1429 (#SNPS) With the person matching all three generations on the same chromosome, we are sharing a common ancestor and likely on the maternal side for her as well as us. Is that correct? ______________________________ For answers to Frequently Asked Questions about mailing lists, please see: http://dgmweb.net/MailingListFAQs.html ------------------------------- To unsubscribe from the list, please send an email to AUTOSOMAL-DNA-request@rootsweb.com with the word 'unsubscribe' without the quotes in the subject and the body of the message
