Will a DNA test tell me specifically where my ancestors came from?

If you do it through one of those ancestry/genealogy companies, they will match your DNA to other people who have taken the test through the same company and agreed to share their info with other customers. You can find relatives that way and most of the people are interested in genealogy so will have their family tree information available or you can contact them (if they agreed to that) and see if they'll give it to you. A standard DNA test will not tell you that information though.

I think 23andme and a few other websites do that type of test.

Lori is right. In one specific case, it can help a lot. Men get their Y chromosome straight from their father.

It isn't supposed to vary, although it does, a trifle. If two men take the Y Chromosome test, and match on 67 out of 67 points, they are both the son of the son of the son of the same man. Exactly how many generations back is a good question, but the more points they match on the nearer their common male relative is.

This assumes both men have their DNA tested by the same company. Usually, however, all you get are some broad estimates of ethnic origin. Sometimes they find a Native American "Marker", so your family legend of "Indian Blood" may have some basis in fact.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
