Micheal O'Neill and wife Nancy Brennan had four children the I know of,being 3 girls and one sone James O'Niell.James was born March 20,1820, in Gorey,Ireland.I know nothing about his sisters Kitty, Sally and Mary. James O'Neill and wife Margaret Edwards came to American in 1848 to New York. What I would love to learn is about his family back in Ireland. His sisters, and his parents. Who his sisters married, about their families down through the generations. Does anyone out their have my Gr.gr.gr.gr.grandfather Michael O'Neill and wife Nancey Brennan in their ancestral three? I have James's linetraced. I would love to find the tombstones of Micheal and wife Nancy Brennan. I'd love to know if James's sisters married and had large families.
