Thomas was a Quaker and a supporter of the Underground Railroad. He married Ann BAILY on 17 October 1822 in the Bradford Monthly Meeting in Chester County Pa, according to information from research done by my grandfather. The family then moved to Ohio. Thomas is listed as having died in Salem, Ohio and Ann as having died in New Garden, Ohio.
The name is sometimes spelled GALBRAITH but our branch of his descendants always seem to have used GALBREATH.
I've been given information that his parents were William and Hannah and that he had siblings: Nathan, Ann, Amey, James & William. I've also been told that other family researchers have been unable to locate a record of their marriage in Bradford.
