Looking for "Louellen" or "Lewellyn" (sounds like/spelling?) who stayed in a boarding house in ASCO WV (McDowell county) during or around 1930. I believe that's a last name, but not sure. He worked at the ASCO coal mine, possibly in a management capacity. Is there somewhere I can find employment records for the ASCO coal mine?

I have searched the 1930 US Census; so far can't find.
