John William Gibbons is the product of an non-paternity event. His great-grandson's Y-DNA matches NO Gibbons but lots of Burk(e)s. As you can see from his profile, his adoptive mother's name was Catherine Burck. I assume his father was a relative of Catherine. My best guess is that the father was from either southern IN or KY (probably in/near Jefferson County). There is some Y-DNA evidence that John's ancestors were from VA.
