I would like to find the county of birth for my great-great grandmother, Grace Branyan Stewart. She was born in or about 1825 in Ireland. Her husband was William H. Stewart, also born in 1825. Their first known child was John M. Stewart. He was born in Ireland in 1846. In 1850, John (then 3) and his mother, Grace, immigrated to the U.S. aboard the ship Patrick Henry. They may have been traveling with James Stewart, born 1805. Grace's husband, William, immigrated several months earlier. The Stewart Family lived in Allegheny City,(adjacent to Pittsburgh) Pennsylvania.
In the U.S., Grace was a member of the Presbyterian Church.
