Hi, Sam! My name's Bree.
I was browsing through Edith's profile and I think she graduated in 1890 rather than 1889—but nevertheless, I have a few characters who would likely know her!
Delight Urquart was a year above her in Hufflepuff. While at Hogwarts her father was Minister for Magic, but before she could graduate a scandal broke over her younger sister being a werewolf, causing her father to resign from his job. She now works at the Ministry.
Grace Greengrass was in her year in Gryffindor. She's not your typical Gryffindor; rather than being bold and boisterous she is nervous and awkward. Her family is practically bankrupt but they're trying to keep the appearance that they're still solidly middle class. She's a debutante but isn't very good at it. I'm not sure if they would have been friends, but they may have run in similar circles!
Frida Lestrange was a Hufflepuff in the year beneath her, but she might know Frida because her elder brother, Kristoffer, was a Slytherin prefect in the year above Edith. Frida was also a prefect, too, and head girl the year after Edith graduated. She's a debutante now and I'm sure their social circles are drastically different, but I'm still listing her because #yolo.
Dionisia Fisk is a few years older but is a working-class mediwitch turned middle-class housewife after she was accidentally impregnated and her best friend's (secretly gay) brother agreed to marry her. She feels very separated from MC society and so seeks the company of other "misfits" when she can, so if they met I think they'd have an interesting dynamic!
@"Helga Scamander" and
Bella Scrimgeour were in Hufflepuff and Gryffindor and graduated in 1887. Helga is a debutante who still hasn't managed to snag a husband and is getting increasingly more depressed by the fact, while Bella had a falling out with her family, fell to the working class, and now works as a apprentice magizoologist. Neither are solid options, but still options nonetheless.
