By checking the USGS website, which lists both current and historical place names, the only reference to Bethlehem that I can find in Tippah County is Bethlehem Church about 2 miles east of Falkner. There is, however, a Bethlehem community in Marshall County about 5-1/2 miles south of Potts Camp on 349. As far as I can tell, no part of Marshall County was ever a part of Tippah County. Perhaps the neighborhood around the church east of Falkner was referred to by the church's name.
