My gggrandfather was Milton S. Dale/Dail who is listed on the 1850 census in Grainger County Tennessee with his mother and siblings. On the 1860 census, Milton is in Wayne County Missouri and married to Mary Camp/Kemp. It appears that several of his siblings have moved to Missouri around the same time. On the 1840 census for Grainger County, there is a James Dail (I think he is the father of Milton), Abner Dail and Abel Dail. It is my theory that James and Abner are brothers and that Abel is their father. I find that James married a Nancy McDonald and Abner married a Jane McDonald - could brothers have married sisters? I would like to share info with anyone working on these lines. Thank you!
