I have an 1891 Biographical History of Pottawattamie Co. Iowa which lists an ALFRED BYBEE, born 1810 in Barren Co, KY, son of LEE BYBEE. They became Mormons and were in Nauvoo, Illinois, then driven west after the riots there and settled in Pottawattamie Co. If you have any interest, let me know. Mona Knight
