Most folks say his parents are Robert Allen and Sarah Elizabeth Walker but I have seen his parents listed as William Allen and Mary Hunt Minge.
There are 2 books out there you might want to find at the library.One is Tennessee Cousins and the other is Allens of the Southern States.
Tennessee Cousins has a section that deals with the family of Valentine Allen and Mary Page.It lists William Allen who is married to Mary Hunt-Minge.
Allens of the Southern States goes into the lineage of Robert Allen and Elizabeth Young, and lists the offsprings of the Young and Drury Allen lines.I believe.
I am descended from a William Allen myself and sorting out which William belongs to what family is probably a life long undertaking.I've seen the same William in so many families it's not funny.I would sure like to find a male Allen descendant from this line to participate in the Allen DNA project.If you know someone, forward them my email address:Cheryl30523@yahoo.com Cheryl
