Nymphadora Tonks
Nymphadora was born between 1st september 1972 and 31st august 1973. She attended Hogwarts School of Witchcraft and Wizardry from 1984-1991, the time of Charlie Weasley, and was Sorted into Hufflepuff House. She never became a Prefect in her 5th year, because her Head of House, Pomona Sprout, said she lacked necessary qualities, such as the ability to behave herself.
