Harriet potter was always neglected by her parents because they think her twin brother Harry Potter is the boy who lived, when in reality the real saviour is Harriet. A few days after Harriet and Harry turned 7, Harriet was soon given up for adoption and since no one knew other than her family or godparents about her existence. After a few months of being in the orphanage, Harriet was soon adopted by her godfather and former best friend of Lily Potter. Severus Snape. Shen she gets her acceptance letter from Hogwarts she was over joyed to know she was going to know she would go to the school of Witchcraft and Wizardry. I don't own harry potter and all credits go to J.K. Rowling. I'll be updating in every Wednesday for this.
