I hope to encourage males with the foregoing surnames to get their y-dna tested. I think a lot could be learned from doing so. My mother was a Kilman with roots to 1665 Maryland and I was very close to my Kilman Grandparents, which explains my Kilman interest.
Prices range from $99 to about $270, depending on the number of markers tested. I am giving the information for Family tree DNA (FTDNA) because it is the largest and I would expect more people to select it as time goes by, especiallyrelated lines in Europe/Scotland etc. The price is more unless one joins the Killman of some other group before ordering the test.
I just found two Kilman cousins that are getting tested.
