Maggie

Maggie is a girl from Megaton whose parents died during a raider attack. She was rescued by Billy Creel, who's been taking care of her ever since. She's a little, friendly girl running round around the town.

If you possess the "Child At Heart" perk, Maggie will inform you of a safe in the floor of Billy Creel's house, and give you the combination (15 16 23 42).
