Because of her mother's Quidditch schedule, Evie spent much of the first five years of her life at her godparents' manor on Montegona and became close friends with the Maximoffs' middle child; Donatello. When her mother married Bill Weasley in 2005, Evie moved in with them though continued visiting the Maximoffs at every opportunity. She began attending the New Alexandria School of Enlightenment in 2012 and was in the same year as Donatello, which she developed a crush on and began dating in 2017.
Evie has been described as being a split-image of her mother. She had the same long, curly dark brown hair; however, Evie's curls are straight while her mother's are a little frizzy.
