I have two of his daughters in my line: Daughter of Mary Fulk - Rebecca Boyles who married William D Cook. Daughter of Cynthia Scott - Martha Jane Boyles who married Hawkins M Cook. They moved to Bartholomew County, Indiana and both died before 1870. I believe too that James Calvin Boyles is a son of William Boyles and not the Calvin Boyles son of Isham Boyles. I would be happy to share what I have.
