DNA testing is the new "thing" in genealogy.
So I thought I would provide some information..I am not suggesting that you undertake a DNA analysis Far from it and I have not done it myself.
It may tell you all manner of things about your genetic makeup but it may not help to break down brickwalls and of course the results are a new science that you have to get your head around....... Great for anthropology.
What I gather from all the people suggesting you take part in a DNA study of a surname is that these studies are for males of that surname. I suppose it then proves that you are a male of the same line as the other males who took part in the testing. If there is a discrepancy then I am not sure about who it proves what. But then perhaps I have not got my head around the stuff either.
This appears to a good article on what it is all about
