The Potter Siblings(on hold)

Harry Potter has an older sister almost one year older. She got a letter from Hogwarts a year before Harry did. It said that she was a witch and that Harry was a wizard. Though she was not to tell him anything until he got his letter in a year.
Well the next year when they got their letters to go to Hogwarts their aunt and uncle didn't want the children to go so they hid, until Hagrid found them like in the book.
Her name is Victoria. She lives with Harry at the Dursley's during the summer.
