Mother Maya is Confessor Cromwell's wife, but they do not announce this to others, as they are both occupied with spreading the ideals of church.[Non-game 1]
Mother Maya is kind, and treats ghouls like Gob with respect and an air of reverence because of their spiritual beliefs.[Non-game 2]
"I'm not one to gossip, but I do know a few things. For instance, did you hear that Lucas wants someone to disarm our bomb? Imagine the blasphemy! I can't believe it! I mean, I don't believe it. He would never do that to us."
Maya is said to be 41 years old in the game guide, but appears to be more advanced in age.

↑Fallout 3 Official Game Guide Game of the Year Edition p.74: "Gob Treated as a freakish, second-class citizen by many people in Megaton (particularly Colin Moriarty), Gob is skittish and nervous, always looking over his shoulder. He does his best to maintain a sense of humor and to be friendly with customers, but this is mostly out of his desire not to be beaten. Confessor Cromwell and Mother Maya treat Gob with respect and an air of reverence because of their spiritual beliefs." (Fallout 3 Official Game Guide Game of the Year Edition Wasteland Census)
