Locations/NPCs of premade adventures

[Griautis]

I'm just starting to plan my campaigns, and I'd be very interested in knowing which locations/characters get involved in which of the premade adventures. That way, if I build an overarching campaign, I can easily find resources on locations I'm visiting. The pinned threads don't seem to have anything like this (just the information of what adventures exist, which will come in handy)

I'm also considering to compile this info myself, however as I'm very new - some help/resources would be appreciated. 

Anyways, first thing first: Is there something like this already available? If not, my next post will probably start something up
