Ann Stephenson

The unnamed woman is a minor character in Red Dead Redemption. She plays a part in the Stranger side-mission "Who Are You to Judge?".

Background
The woman herself has some shadows of the Bonnie MacFarlane character in her personality. Like Bonnie, she clearly enjoys her sardonic sense of humor, coupled with relentless teasing. She also appears to be a "headstrong woman working in a man's world," as she is both armed and wearing more masculine clothes. It is implied that she might be an outlaw or bandit of sorts, as she is in Tumbleweed and claims to have "taken" Lucy from Jeb. She doesn't seem to mind going with Marston to return Lucy, however. She remains in Rathskeller Fork after the completion of "Who Are You to Judge?".

Interactions
Marston will find her in the stables near Tumbleweed, grooming a horse. He will immediately assume she is Jeb's "love" whom he has been sent to retrieve. She corrects him by revealing that Jeb's love, Lucy, is in fact the horse by which she's standing. She frequently expresses her amusement at Marston's confusion, much to his chagrin. After the side mission shes never seen again ( confirmed )

Trivia

 * The unnamed woman carries a Schofield Revolver, which the player would usually first obtain from Landon Ricketts in Mexico. Killing her during or after the mission allows the player to obtain this revolver far earlier than usual.
 * she some what looks ellen the Lady from The quick and the dead.
