Thank you. My DNA matches Killian and some Harrelson around the same period. My grandfather was probably adopted. We have Y-DNA confirmation that he does not match his father. He was raised in OKC and was known to have visited cousins in Texas as a youngster at least once. His mother was thought to have never had a child of her own by her kin and was only a parent in her marriage to only one. Any ideas may be helpful.
