Mrs. Johnson who allegedly also goes by "Hawkeye" Johnson, is the mother of Jeremy Johnson and Suzy Johnson and wife of Jack Johnson. She is the sister-in-law of Joe Johnson and probably the daughter-in-law of Hildegard. She is also related to Annabelle. She is in the Free-Form Jazz Band alongside Linda Flynn-Fletcher and Vivian Garcia-Shapiro. She has appeared several times (mostly in background shots).
Suzy and her mother have yet to be seen interacting but it is safe to assume that she is unaware of Suzy's darker personality.
