I am trying to find out about my Great Great Grandmother Susan Galbraith who was born in the Raphoe, St. Johnstone, Strabane area in 1832. She was married in about 1852 to James Duffy and they later moved with their children to Philadelphia. I know nothing about Susan's Galbraith family. I believe there was a family dispute and she lost touch with them. Would love to hear any relevant info or get a pointer in the right direction.
