Thank you Cheryl for you interest and question. Your Question points out that I should have given more about what the test is for and about. Because an explanation is long, I will refer you and (any Kilmans/Killmans etc)to the following Harris link which gives a better explanation than I could. It gives a pretty good reason for the goals for testing.http://www.harrisdna.org/http://www.harrisdna.org/
The reason I think Killman's and variants of the name should test is that we will be able to prove or disprove shared or common ancestors. I can trace my Kilmans to about 1710 Maryland, but I hope to find where they came from (Scotland? Ireland? Europe? etc.). If anyone does not care where their ancestors came from, they should not waste their money on getting tested. Unfortunately, until several are tested, little will be learned unless we get real lucky. For example, the only Killman tested so far, has roots to Austria. If anyone matches him, they would have a common ancestor. I personally think the Maryland Killmans came from the British Isles, but?
I am going to give my phone number for any who wish to call about Y-DNA testing. If one wants, give me their number and the call will be on me.
