I haven't had the DNA test done yet so I'm hoping somebody here can help me decide whether the maternal DNA test will work for me.

I believe that my mother was adopted. She is an only child born in the 1940's. Her mother had told her she was 40 when she had my mother but when her mother passed away we found out that she had lied and she would've actually been 50. A 50 year old woman having a baby today (with a lot of help) is shocking enough but a 50 year old woman in 1943 having a child is, I think, pretty impossible sounding.

We have nobody to ask because everybody in my mothers family had long since passed away (we buried the last Uncle in 1990).

What I want to know is this - she was raised in an Irish Catholic household as an Irish Catholic. If I got the maternal DNA test done will it tell me whether I am actually Irish or not. The funny thing is, my mom and I always get mistaken for being Jewish and I thought that maybe, if she is actually adopted (no way to find out, already tried), if the test can tell me if we are Irish or not that will help us to answer the adopted question. If the test can't answer that question then there is no sense in me having it done.

Any answers anybody could give me would be greatly appreciated.

Thanks!

Nat
