You are the first person to request it, so you are the "winner". Haha. What I mean is, I'll write you privately to let you know the cost, and if you still want to do it, then I'll send on the required email to FTDNA telling them that you want the special introductory priced test. They in turn will contact you and let you know if they need a fresh sample or not. If they do, they'll send out another DNA kit. If not, they'll just use the vial they already have on hand at the lab.
I agree that you will likely be able to find 5th or 6th cousins, but it will get harder to find ones earlier than that. However, my Heaton cousin is further back than that, and she and my aunt do share one identical DNA segment. I believe they share .28% of the same DNA. That's POINT 28!! So, it's possible to find common ancestors back to the 1600s, and who knows, maybe further!
What is cool is that, any matches that you have, once you've identified your common ancestor, that PROVES that line!! So, autosomal DNA can prove several lines, whereas Y-DNA can prove only ONE line, and mtDNA can prove only one line!
It will probably take awhile to have lots of matches, as FTDNA builds up their database with other people who take the Family Finder test. But that was the way it was (and still is) with their Y-DNA and mtDNA testing. Just takes patience to wait for those matches to come in!

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?
