Check with the cemetery office to see what they may have on him. If you're lucky it will have the town he was born in. Also check with the church he was a member of for the same reason.

His obit may have the town too. It may also have any surviving siblings which at his age is a long shot as he might have outlived all of them, but don't assume especially since he could have been born much earlier then they were.
