If your new guy is kit number 28378 then FTDNA or whichever lab did the P19
test should perhaps be ashamed of themselves for taking someone's money for
this test. With the 8,9,8 at DYS 459a,b; 455 and exact matches with three
who also have 19,21 at YCAIIa,b the STR evidence is virtually almost as
complete as any SNP test. And one would do the test or be advised to do the
test only in the extreme cases of wanting the last ounce of certainty.
These haplotypes are called I1a for very good reason.

> Hello,
> The Clendenin project has 29 members, all but four are R1b. The other four
were suggested as an I. These men, all four, are 25/25. Three of them have
extended to 37 markers where they match exactly (I am fairly confident that
if the fourth extended to 37 markers he would also be a 37/37 match).
> My question is this: The man who has tested to 25 requested a SNP and
received a definite I on a P19 test.
> Would I be correct in changing the haplogroup on the other three men to a
definite I rather than a suggested I based on their 25/25 matches?
> They're actually I1a but if I understand correctly FTDNA doesn't test to
that depth??
