Okay, so. Obviously Regan does not know him AT ALL.
Marlene (lion_at_heart) probably worshipped him. She would've known him, too. In the 71-72 school year, she was a reserve Chaser for the Gryffindor team, and then in 72-73, she made starting Chaser, and has been ever since. But she was probably all "OMG COOL OLDER QUIDDITCH PLAYER, I WANT TO BE JUST LIKE YOU ONLY FEMALE" (kinda how she is with the Aurors, lmao).
Helana (hel_bakes) ... has no idea who he is, sadly. She started in 73, so they weren't even ever in school together.
