Eleanor Goldsholl Gordon gave a number of suggestions as to how to word an
e-mail of a "DNA match".
I'd like to add one item. It makes a huge difference if someone is a
perfect match with 12 markers versus a perfect match with 67 markers. I
would not think it worth responding to a perfect match at 12 or 24 markers,
nor would I respond to a 67 marker match at a distance of 4, except for a
rare haplogroup like my T1a where I have few matches at all.
I too have submitted several DNA samples of my male ancestral lines, and
people matching assume I have only submitted one, probably like them.
