I am looking for documentation on the parentage of William Seaman born bet. 1735 - 1740 possibly in Hempstead, Long Island, NY and died in Washington Co., PA. He was a Quaker. We believe that his parents were Nathaniel Seaman and Sarah Powell, but have no documentation. Between 1760 and 1763 he married Amy (possibly Amelia) Disberry or Disbrow who died before 1785 in NJ. I would also like any information on her.
