Trixie Grimm was the great-aunt of Sabrina and Daphne Grimm. Being a a member of the Grimm Family, Trixie was actively involved in Ferryport Landing's Everafter community as she took on the family business. Like most Grimms, she kept a journal that detailed her exploits, particularly with the Book of Everafter. Trixie was born to Josef Grimm and Anna Grimm in 1975, the same year as her sister, Vesta Grimm. It can be inferred that they are twins. Trixie had an elder brother named Peter Grimm, who was the great-grandfather of Sabrina and Daphne Grimm.
