Deanna was born the youngest triplet. As a baby, she was given up for adoption by African Americans Jack Blunt and Marcia Courtney Thompson, who were in Pine Valley at the time. She was good friends with Edgar Louis Quartermaine, himself the first birth child of Charles Montgomery Burns, until they grew apart when her adoptive older sister Mary Mae Blunt fell in love with him.

As she grew older however, she became fond of carnival burlesque and went on stage alone for the first time in her life, only with both her bra and her classic briefs on. The African Americans of Pigeon hole were truly laughing at her, even though she was offended less by them but more by her birth family's neglect.

She was very proud of her burlesque stunts, although time ran out for her as her once promising career came to a halt. As a result, she retired from burlesque and became a long time schoolmarm at Springfield High school.

Deanna was also perhaps the first mistress of Abraham Simpson Jr and the actual birth mother of his son Homer Simpson. She died in Springfield in 1995.
