Bellatrix Lestrange (née Black) (1951—2 May, 1998) was a pure-blood witch, the daughter of Cygnus and Druella Black and elder sister of Andromeda and Narcissa. She started her education at Hogwarts in 1962 and was Sorted into Slytherin. After graduating from Hogwarts, she became a Death Eater, fanatically loyal to Lord Voldemort. She was one of the few known females in the group, as well as among the most dangerous and sadistic of Voldemort's followers. While Bellatrix and Narcissa married pure-blood wizards, Andromeda married Ted Tonks and was disowned by the family. At the end of the First Wizarding War, Bellatrix, her husband,Rodolphus Lestrange, his brother Rabastan, and Barty Crouch Jr.took part in the torture of Aurors Frank and Alice Longbottom to the point of insanity, while searching for information on Lord Voldemort after his first downfall.
They were caught, and sentenced to life imprisonment in Azkaban for torturing the two Aurors, but escaped in the 1996 mass break-out, along with nine other Death Eaters. She participated in several battles of the Second Wizarding War, making it a particular goal to kill any relatives who were members of the Order of the Phoenix, including her cousin Sirius Black and niece Nymphadora Tonks. She also killed the Malfoy family's former house-elf, Dobby, who had become a firm ally of Harry Potter. During the battle that ended the war, she was the last Death Eater standing, apart from Voldemort, but was eventually killed in a duel with Molly Weasley.
