Hi again, Susan!
I suppose that in some families (for example, our Townsends), there
will be thousands and thousands of close matches. I know that the
Quaker community back then was very close, and people tended to marry
back and forth between families; the Pearsons and Townsends, the
Cains, the Parsons, the Cadwalladers, Coxes, Wheelers and on and on.
My husband (a stemcell biologist) tells me that autosomal DNA testing
is more "unstable" the further back it looks, and therefore it is most
useful for the first several generations; and, another nice thing
about it is that the test looks at more markers than the yDNA or
mtDNA, and so the likelihood of finding more matches is greater. I
think I may go ahead and do this test; do you know if ftDNA can use
the sample from our Townsend man that I sent in a few years ago, to do
autosomal dna testing, or will it need to be a fresh sample?
