So, Hermione's her year but idk if they'd really know each other? Evan would know her, if only because he sometimes bartends at Sirius' pub, too (when I remember that he does, at least).
Idk about the rest of mine. Roger could have totally briefly dated her in school? He's two years older than her...
But yeah, Aisling, Higgs, Oliver and Jun are unlikely to know her (though Aisling totally says she must, because Laurel's Axel's baby sister!).
