There is a book at the LDS (Mormon) Library on the family of James STARK of Stafford Co., VA, who is probably the immigrant ancestor of this line. There are also DNA projects that have identified descendants at FamilyTree DNA com. Do you know a male relative with the surname STARK? James STARK had a brother William, 28 in 1910, and a son James, 5 in 1910.
