Mrs. Chilton worked as the housekeeper for Philip Wayne and she became close friends with Philip's nephew, Bruce, who became his ward after his parents, Dr. Thomas Wayne and his wife Martha, were murdered.
Because Philip was rarely home, as his work required him to travel quite a bit, Bruce was put into Mrs. Chilton's care. She witnessed the growth of Bruce into a man and years later, she learned that her son, Joe, was responsible for the murder of Bruce's parents, which eventually cost him his life. After losing Joe, Mrs. Chilton lost Max when he confronted Batman.
Despite knowing that her sons were criminals, she never revealed this truth to Bruce, and they remained friends. Mrs. Chilton was also aware of Bruce's secret identity as Batman, but she also kept this secret for herself.

Even though versions of the character may have since appeared, this information does not apply to those versions.
- Mrs. Chilton is presumably a widow, as no mention is ever made of a Mr. Chilton.
