Hey Fox Spirit! I honestly thought I had a bunch of people right around her age but it turns out all my characters got old while I wasn't looking >.>;

So really the only thing I can offer you is Reuben Crouch - a few years older than her but would have been at Hogwarts around the same time. Ben was a Gryffindor and remains to consummate Gryffindor - impulsive, bold, thrill-seeking. He probably wouldn't have noticed her in school much if she was shy, but he was fairly popular so she might have known who he was. He is technically single and hurlable, though he's not really great husband material because he's generally reckless and irresponsible and has a reputation for being so. If they were to run into each other somewhere he'd probably flirt even if he wasn't particularly interested, because that's what he does. Let me know if you want a thread ^^

EDIT: OH HEY I FORGOT all my characters getting old means my younger characters also got old and now Tiberius Lestrange is in his late twenties. xD They would have been in the same year and house at school! Tiberius was reclusive and brooding at the time. He performed very well in his classes but was more interested in his own projects and personal studies. After school he betrothed himself to a younger student, spent a few years traveling and working, and then married her right after she graduated.

Since they were in the same year/house they couldn't really have gotten by without knowing each other, but Tiberius is antisocial so he might pretend he doesn't recognize her if meeting her out and about. I'd still be down for a thread, though, because that sounds fun xD
