Safe Combination?

[Mögbär]

Any hints on where to check for that? I already know what it means, but can't find anything about how to learn the exact numbers. I do remember a comment about what age the couple married, but can't find it anymore, not in the journal and not in the surroundings. It could help with the year if I compared that info with the years from the tombstones, but the combination has six numbers, so it will require more than just the year, too.

Help, please? (Am playing this on PS4, by the way, don't think it makes much of a difference, though.)
