Ok, so I know Dean and Sam can't be found by Angels or Lucifer but can Bobby be found?

What town and state does Bobby live in?

1. Does anyone know from any canon when Bobby's wife died? and exactly how, or is it intentionally vague (hoping for b)

2. Is she ever named?

I was guided here in the hope someone knew the answers, if it's it never answered it's never answered and I can make it up xp
