Hey Brielle!

Persephone is fab and Carmelina Cramming will absolutely think that too. She's currently the Ancient Runes professor! She married a cursebreaker to go round on archaeological digs and do research and when he died, she came back and took up teaching. A former Ravenclaw as well, she's also a lesbian (terrible at making moves but currently making eyes at one of the house matrons). That to say, I think they'd get along pretty well and Carm would definitely be game for all the nerdy archaeological talks and maybe the occasional bit of gossip. xD

In terms of students, I have Nelson Higgs and @"Jemima Farley". The latter is a high-key mess of a teenage girl at all times and possibly has done more crying in the library than studying, but the former likes his theory so is definitely a library geek.

And for people she might have known in her schooldays, my best bets are probably Porphyria Dempsey (Ravenclaw in the year below) who is now a spinster poet and an absolute weirdo in society, and Jude Wright (Slytherin in her year) who now has a merry band of progressive ~revolutionary friends in London but who would have been already quite interested in all kinds of suffrage and equality at school.
