I have some info.Mary, Nathan & Virginia are not in the same household.A closer look at the census page shows that Albert is HH# 167 and Mary is in HH#168. Albert (son of Valentine and Parthena) and his cousin Henry (son of Littleberry and Mary) married sisters, last name Colvin. Mary Huff is the widow of John W Huff (b 1834 GA, d. 1862, Canton, MS) I believe that John Huff is the son of Littleberry Huff, brother of Valentine Huff, moved to AL from GA in 1857.(Albert and John would be cousins).Nathan is not a Huff, he is a Pate, the son of John Pate, Mary's 1st husband.If you go down to the next household on the same page, you will see one of her other sons, Eli Pate.She had 3 sons from first marriage. Virginia, (age 9, 1870) is the only child of John Huff.She is my great great grandmother.
