OK, so I was wrong!!Contrary to the Hanover Co. census taker, these two Mary Duggins' ARE the same.Found proof in the Chancery Ct. records online from the Library of Va. which state in a court case that PH Duggins' wife, Mary Eliza Nuckols, was the same Mary as the widow of Bowlman (spelling ?) Bowles.
So000...I'm sorry to have been such a pest in this matter, but nobody ever provided me with any proofs, despite my many queries, letter, etc.,so this Yankee may be forgiven, I hope.
Keep those cards and letters coming! At least, now I know which Mary Nuckols -Elizabeth, not Elmira - was my late husband's great-grandmother. She was the daughter of John William and Susan Jude Nuckols.
