 Walker's daughter, Mary, was her primary companion at the lighthouse for the majority of her childhood; her brother Jacob spent most of his time on the mainland as his mother's postman and general courier.Jacob did continue to make daily trips out to the station to help his mother tend to the light.Mary eventually spent more time on Staten Island as well, as she boarded with a family there once it was time to go to school, only returning to visit on weekends and holidays.
