Sister Maggie Murdock was created by Frank Miller and David Mazzucchelli, first appearing in Daredevil #229[2] in 1986.
She and Jack had Matt when they were a young couple, but Maggie soon suffered from postpartum depression, having doubts, feeling constantly anxious regarding Matt's safety, thoughts which soon developed into self-loathing, feeling estranged, as she considered herself to be a bad mother.
Jack managed to stop her; Maggie broke down and hugged her husband not knowing what to do with her illness that she brought to the family.
Nearly broken after trying to get revenge, Murdock was taken in by Sister Maggie and with his enhanced senses, immediately felt the connection between them but he never knew that she was his mother.
Years later, while caring for a baby girl he suspected of being the Antichrist, he almost threw the baby off the roof of building trying to kill it but soon realized he was wrong and plunged off the roof, saving her and himself, ending up in front of the Church where Sister Maggie lived.
Daredevil brought her to Sister Maggie at the Clinton Mission Shelter and slept for two days in her room.
When he questioned all the problems he had had in life and told her that God had let her off pretty easily, she slapped him across the face, and he dropped to his knees and apologized.
In What If vol.2 #2 (April 1989), Sister Maggie cared for Karen Page when she arrived at the church seeking help from a man named Paulo Scorcese and her own drug abuse.
vol.2 #73 (March 1995), Sister Maggie attended her late husband's Jack Murdock's funeral.
