I know this was posted a long time ago, but I am the grand-daughter of Lottie's brother Artis Lee Gaskin. I would love to know what information you have found regarding the Gaskin family...here is a brief summary of what I know (which may or may not be precise)
Artis and Lottie's Father's name was Therso Marvin Gaskin. His parents were Francis Marion and Louetta Hester Gaskins. Therso dropped the "s" in Gaskins. Francis Marion's father was George W. Gaskins Jr. who married Lydia Miles Gaskins. I am pretty sure they had 3 children, one of which was Francis Marion. The other was Ebanezer Jackson Gaskins, but I am not sure of the other child.
George W. Gaskin's Jr, father was George Gaskins Sr. who married Elizabeth Madrie in GA. I am thinking his father's name was Thomas Gaskins. There were so many Thomas Gaskins, I kind of have lost it from there. Please let me know if you know anything further.
