I read your messages, I have no idea who Nancy is. My ancestors are Preston Allen and Lucy Boyd of Franklin County, Virginia. My Preston went missing from Franklin after the 1830 census, Lucy and at least five children lived later in Patrick County. Creed, their youngest son was born in 1837. It is only my assumption that the Preston in Kanawha County is the same man, there is no hard evidence, only circumstantial.
The marriage record for Preston and Winney Pauley lists his parents as William and Rachel and that he was born in Franklin County. Rachel's surname isn unknown and the Rachel Keeran you mention is someone who needs to be checked out. I am also looking at Rachel Kendrick wife of another William Allen.
Do you know when and where Preston Allen died? If his grave could be located it may provide more information.
