1. Avengers Family
2. Spider-Man Family
3. X-Men Family
4. Fantastic Four Family
5. Marvel Cosmic Family
The first four are represented at Universal's Marvel Superhero Island....but Marvel Cosmic is not. The closest they have is Thanos, but because Thanos debuted in Invincible Iron Man #55,
he's actually part of the Avengers family.
Anyway, Cosmic Marvel started in the 1960s with science fiction works known as "Fantasy Masterpieces". FM was an anthology series inspired by EC Comics' horror anthologies (Tales from the Crypt, etc), but given the science fiction veneer that propelled Star Trek. "Fantasy Masterpieces" lasted for eleven issues before being re-branded as "Marvel Super-Heroes", at which point they introduced Adam Warlock (#12) and the original Guardians of the Galaxy team (#18).
