all the faces up to emily are for cousins! i'd love to see emily as one of liv's paternal cousins, and you'd get two more cousins in-game, too. florence is for a maternal cousin, possibly even as ~ganesh's step-sister? jodie is for ~kerchief's younger sister. i know they were hoping the two of them would be close, but i don't know too much outside of that.
every other face is for a best friend of hers from the uk!
