Minnie Mouse’s parents are unknown, but Marcus Mouse may be her father’s name. His name was first used in the comic strip story “Mr. Slicker and the Egg Robbers” (published 22 September — 26 December, 1930). The same story featured photographs of Minnie's uncle Milton Mouse with his family and her grandparents Marvel Mouse and Matilda Mouse. She also has an uncle named Mortimer Mouse and twin nieces, Millie and Melody Mouse.
