I am sorry I don't have any information on Alfred Jenkins.
Ann R. Sparks was a Burt before her marriage, her fathers name was Richard. They were from GA, as was Giles Sparks.
Giles was the son of John Sparks and Elizabeth Wilkerson/Wilkinson Sparks of Harris County, GA.
Ann I believe was born in Putnam County, GA, her parents later moved to the Columbus GA area. That is really all I know of her.
I am sorry I could not be of any more help.
