I see some references in old books to the local papers around that time being the "Idaho News" and the "Blackfoot News". The current local paper there is the Blackfoot Morning News, phone number 208-785-1100. The number to the Bingham County Historical Society is 208-785-9906. If you want to make a few calls and figure out if any of them have 1902 newspapers in possession, I don't mind driving down there and looking through their archives for 1902 birth records. "Craven" is a name I've seen around this area, not so much "Cravens" but who knows.
