I'll start with a couple of easy ones:
Clementine Lepp, Philip Swinford, Tommy Harden, "Thunder Boy" Nabbe, Willa Mae McGowan.
4GR left, 1 Upkeep, 5 Influence, 1 Stud and another who can become a stud when facing wanted dudes. Clementine can swap for Hattie DeLorre for extra wanted dude hate, higher value and the Deputy keyword at the cost of 1 more GR.
Irving Patterson, Luke the Errand Boy, Chuan "Jen" Qi, Diego Linares, Nicholas Kramer.
4GR left, 1 upkeep, 5 Influence (6 if Jen gets a horse), 2 Studs, 2 Mad Scientists. The home ability can also make Luke a 2 Stud. Luke can swap for Maggie Harris for Horse-based decks for the cost of 1 more GR.
