Here's the map if anyone needs it!

Helga, Flora, Dionisia, Eldin, and Orinda live in Hogsmeade but I have no idea which street because they're adopts (or in Dio's case she's married and moved in with Ari somewhere in Bartonburg :P)

Soph and I decided that Priam & the Lestrange girls (Frida, Gretchen, Meta) live on Imperial Square in Wellingtonshire. Bella lives in the Hog's Head. I imagine Handsome lives All Hallow's Place with his sisters. Freddie rents a home from his sister on Morgana's Crescent, probably. Archie lives in the North Bartonburg part of Fancourt Court.

I think everyone else lives outside of Hogsmeade. Cammie lives in Godric's Hollow. Charity's in Swallowbury in Irvingly. Ernie, Holly, Lyre, and Wiley live in London. Finny lives in Ireland. Edric lives on the Isle of Sheppey. Hortense lives in Wales.
