I am in the process of discovering my ancestors from Irealnd. My grandmother was Mary Woods and she lived in Armagh. She came to America either alone or with her sisters Alice and Katherine. Mary died in childbirth giving borth to twins. She was married to James Woods and he left after her death (the twins dies as well. Mary left three children, one of whom was my mother Katherine. I do not know for certain yet when she left for America but it could have been around the same time that your mary left.
