I signed up for a month subscription on the world thing. That must be the same thing. It really doesn't seem to be much help here.
I have googled the name. I found a couple sites like Findagrave.com where it shows his tombstone. It's the same Louis Devine I found on JewishGen here, but I can't know for sure if it is the man I'm looking for. All the relatives who could tell me anything are dead, so I don't think there's much else I can do.
