I have:
Merengue, Cheri, Blanche, Skye, and Bruce- live in my town now, got for favors and petitions and the like.
Goldie, Kyle, Pompom, Egbert, Cube, Curly- used to live in my town, got either from running errands or sent when they moved out.
Felicity, Stitches, Marshal, Anicotti, Keaton, Gaston, Ava, Quilson, Ruby, Pekoe, and Snake- got via trades with other players. I'm trying to collect all the pictures!
Oh, and I have Jingle's as well.
