Are there any fics where Henry Winchester goes to a different point in the supernatural timeline or an alternate version of Supernatural

Any fics where Sam and Dean get to a chance to know their grandparents whether that's Henry surviving in their timeline or they get to know a different grandparent(s)

Anything where the boys' kids get to know John, Mary, Bobby, or Ellen as their grandparents.

Help would be much appreciated.
