I think he means if the accounts match, each person is given a unique account id So it's matches those, not the names -----Original Message----- From: Andreas West via <genealogy-dna@rootsweb.com> To: Jim Bartlett <jim4bartletts@verizon.net>; genealogy-dna <genealogy-dna@rootsweb.com> Cc: Jim Leahy <j_leahy01@nc.rr.com> Sent: Tue, Dec 15, 2015 8:24 pm Subject: Re: [DNA] Basic ICW Questions: That's kind of surprising, Jim. Do you mean that if you and I match on FTDNA and we both have John Smiths in our matches (albeit different people with that common name) then: - one of them - both of them Would show up as ICW? I can't imagine they go just by name. Here's what I think they do: 1) all matching segments between two people are in a table 2) if you (A) and I (B) have a third person (or more) irregardless of the exact position (as the table only store the status of who matches with whom, not where as where could be more than one record/segment) then it would show this third person as ICW to both of us So it's based on atDNA but it's missing the detailed information needed to do triangulation Andreas > On 15 Dec 2015, at 23:00, Jim Bartlett via <genealogy-dna@rootsweb.com> wrote: > > Jim > > The ICW algorithm does not include arDNA. It does not include genealogy.
