I have pretty much the same info. The only real documentation is that he is buried in Hesper Cemetery, Hesper, Winneshiek, IA (1852-1882). In 1880 he is living in Hesper with his father and his occupation is listed as carpenter and preacher. In William G. Cutler's History of the State of Kansas, he is cited under his father-in-law's biography, as Rev. Joel Battey of National, Clayton, IA (where I am guessing he may have died). The Pilgrims of Iowa (Congregational Home Missionary Society of Clayton, IA) mentions "Joel Battey, native of VT 1852, National, Granville 1880-1881, died July 1882". He was the son of Nicholas and Martha Hoag Battey and was born in Starksboro, VT not Starksville. He married 24 or 28 Dec 1880 to Mary Etta (Marietta) Root daughter of Lysander and Nancy McDonald Burns Root who remarried to Cortez Brown after Joel's death and resided in Oklahoma City where she presumably died, in 1948.
