Abigail (John's wife) was a member of the gang.
Of course, she was also like a young prostitute, so uh, that might be hard to integrate into the game.
Though it's clear in RDR we're hardly meeting the entire gang (especially since there's 7 people in the image and we only met 5) so there really isn't much story to retcon given we never got the full picture anyway.
No, I would love to see the posts if Rockstar decided to cast her as a lead in the game, still being a prostitute and all...
