My grt grt grt grandfather was Aquilla Nail. To the best of my knowledge the Nail family came from VA, fought in Rev. War in GA, some moved to TN, my Aquilla, who m. Sally Lee, moved to Oregon about 1862, when he was an old man. Sally had died around 1852-3, Aquilla remarried, wife died, he remarried again to a lady named Smith, who died enroute to Oregon. Aquilla lived to his death in 1869 in Lane county, Oregon. I don't know if this will help you or not, but might give you a lead.
