She was sorted into Gryffindor, much to the dismay of her pure-blood fanatic parents, and became quick friends with Lily Evans and Remus Lupin.
She often became the target of Sirius Black and James Potter's pranks, until her and Lily decided to seek revenge for the boys cruelty.
Her and Sirius eventually grow closer and begin to date in their 6th year at Hogwarts. They get married two years after they leave Hogwarts and their only child is born on the 9th of February, 1981.
