Larry, It is possible that your John Nail is related to my Charles Nail.Charles Nail's father was Aquilla b. 19 Nov 1785.The Aquilla Nail family was in TN for the 1880 census.One piece of information I found indicates that Aquilla had a son named John R. Nail, but his birthdate was 1814.
Is it possible that the birthdate of John Nail b. 1827 is incorrect?With that birthdate, I would think he would have been too young to have fathered the John Nail b. 1834.If the date is incorrect, perhaps my John R. Nail b. 1814 is the father of John Nail b. 1834.It also might make Charles Nail and the older John Nail brothers.
One thing I have found out about the Nail's is that there were 2 or 3 Aquilla's born about the same time and living in about the same areas.They are an interesting group but hard to track (I almost wrote that they are hard to "nail down")!
Let me know if you think our Nail's are related. Connie
