Oooo I have Irene Crawley who's now at the National Portrait Gallery but used to live in Hogsmeade! I feel like they'd get along quite well. Then I also have my Hogsmeade ladies, Saffron Whitby, Rowan Yaxley and Veronica Gallivan — there's also Benedict Sterling who is gay and in need of more friends >D

And since you're down for unconventional friends may I put forth Hestia who also used to live in Hogsmeade but is now in London xD
