Your message is very old, but I'm hoping you'll see this reply. I am also researching this same family. My grandmother Grace Lyles was adopted by Randolph Lyles and his wife in 1901, but I've suspected that there was a biological connection between my grandmother and Randolph. my suspicions have just been strengthened, because I've taken the Ancestry DNA test and have just matched up on the 4th cousin level with someone who has a great-grandmother with a Lisle surname - a variation of Lyles. i've found an "Albern T. Lyles" in the 1870 census living in Mississippi - town of Cohoama or similar spelling. I am trying to determine who Almon T.'s parents were so I can make the connection between my "Lyles" and my 4th cousin's "Lisle" ancestry, plus ascertain who exactly my grandmother's birth parents were.
