Nymphadora Tonks
Tonks, as she is known, is the only daughter of Andromeda Black and Ted Tonks. She is a Half-Blood, but both of her parents are actually magical. Her mother is a pureblood from the ancient wizarding family of the Blacks, and her father is a muggle born, therefore considering that the majority of her father's family are muggles she is considered a half-blood, even though he is not a muggle himself. Tonks is a metamorphmagus, which means that she can change her appearance at will. Her Patronus is a jack rabbit, but it changed into a wolf (Remus's Patronus) due to her love for Remus Lupin.
