If he owned land maybe there are land ownership records at the courthouse? Since he was here in 1930 maybe the census would give a better idea as to where he lived, have you found him on the 1930 census? I dont have access to that year or I would check it. The Roberts funeral home that did his funeral is no longer in business and so far I havent been able to find any records left from their time in operation...I would guess land ownership records would be the best way to go as to finding his exact address. That is if he owned land.
