I am in search of information on Joseph Croyle born circa 1812. His daughter Christena was my grandmothers grandmother. My grandmother Nancy Rose Williams Molet is 96 yrs old. By the age of 14 she was orphaned by both parents and grandparents. Their were 11 Williams children, 9 of them girls with 2 boys the youngest. She grew up and married in Pennsylvania then migrated to Oklahoma. All of her siblings have preceded her in death. She is trying to prove her lineage and I am stumped as to who Joseph's father is. I have found nothing that proves who it is. The search for Truth by Wallace Croyle alludes it was David Adam Croyle son of George and Barbara(Miller) Croyle. Any help or direction is greatly appreciated.
