Narcissa Malfoy

Born Narcissa Black, Narcissa is the middle daughter of Cygnus and Druella Black. She is the middle sister of Bellatrix Lestrange and Andromeda Tonks, though Andromeda is not considered a member of the family by the vast majority of Blacks due to her muggle husband, Ted.

She was born in 1975 and attended Hogwarts from 1986-1993. Like her husband, son and older sister Bellatrix, Narcissa was a Slytherin.

Lucius and Narcissa married after her 7th year at Hogwarts and in 2000, the couple had their only child, Draco.
