Hello Dorothy: Late in reading you post from 2003 regarding Young Allen.
In seeking my Allen kin, I found a record of a Robert Allen who married Elizabeth Stokes, same dates as the Robert you mention.Also had a son Young Allen, same birth year as the Young Allen you mention.
Not knowing for sure which Young Allen may be my line, I'd like to have any info on this family. I'm told that my ancestor of Wake Co NC, C.A. ( Coleman Anderson) Allen bonr abt 1765 is son of one of the men named Young Allen. My C A Allen and family removed to VA circa 1830. Thanks Deb
