Thanks Kelley, I am starting to think he may be the right one.The problem is this, if you look at the Bosque in 1870, it appears as a different family, different wife and children. I will definitely look further into Cass County. It appears as though there are additional Allens that stayed in Cass, although William disappears. Also the wife in Bosque, 1870, is Martha Ann Blue who is much younger and she is definitely from Bosque county. Do you know how I can request copies of Civil War Pensions?
