Thank you very much to everyone who replied to my post. In terms of some of the questions asked, the Haplogroup is the common R-M269, and the match at the 25 marker level is a genetic distance of 2; there are no matches at any genetic distance at the 37 marker level. In this respect I have a very similar pattern to those John Cordes mentions in his post (including a lot of perfect matches at the 12 marker level), so it is reassuring to find that the results I have so far are not unusual :o) What I’ve learnt since getting my results and asking these questions is that no matches at the 37 marker level is a not necessarily an unexpected outcome, and that my focus must be on DNA testing within my surname study. Many thanks to all for the comments and advice. I am off to do some reading and research now ;o) Tanya
