I am trying to trace my ancestor JAMES DINSMORE who was born in Ireland circa 1750/1754. His wife was named MARY and they are known to have had at least four children - THOMAS, SAMUEL, REBECCA and JUDITH. James died in Amhurst Co., VA before 1789 when son, Thomas, married. Mary was still living as she signed for Thomas to marry. Samuel, who married in 1799, signed when his two sisters married. Has anybody heard of this family?
