Hello Shane - Here is one opinion.
Have you looked at one-name projects that are mainly R1b ?
Of course, I have a vested interest - but you may like to look at the genetic
testing reports on www.brookingsociety.org.uk
In my opinion 12 markers only show who is worth testing further, and
25 markers are now the minimum requirement.
But .... I suggest that for every different R1b pattern of 12 markers there
will be many thousands of people with it.
At a guess, maybe 50,000 in the US and 10,000 in the UK.
A few of these people will be from the right family - but most will have
convergent patterns. I.e. mutations from their main line towards your line.
So, overall, unless the surname is very unusual I would not suggest
testing 'strangers'. And, test only people who have a really good
chance of being closely related.
Lots to be thinking about. Any comments ?
