OKAY SO. I could give Ezra a sister if you don't want a native. She could maybe be motivated to show up after finding out about their nephew and Ezra getting married and settling down here.
There's also a Marshall sibling available around 28ish! The youngest three were kind of all back-to-back, so we could work her in between Elijah and Edward! I'd probably want to change her name to something else just because I don't want to completely retcon Elle (she could be an off screen cousin like we did with Hunter), but otherwise that's open :)
