Marnie Chandler was born in May 1932. She didn't share much characteristics with both parents, so she had been in the boarding school for decades. She wasn't chatty, but her various (and often unwritten) crimes at the boarding school pretty much prevented many of her teachers from ever attending school again. She also had the luxury of abusing Christopher Corlandt for a long time, because she was the real force behind his operation.
Because she didn't care for her classmates, she became a successfully ruthless teacher herself. She remained single for much of her life until she died in 2010.
