Alice Lestrange

Alice Iris Lestrange (born 3 September, 1958 - 6 October, 1996) was an English half-blood witch and the second daughter and second child of Marlin Lestrange and Iris Lestrange (née Grenville-Clarke). She attended Hogwarts from 1969-1975 and was sorted into Slytherin House, like most of her family. Her family was a very minor branch of the Lestrange family and was very distant from the main branch, so distant that the children from the main branch of the family didn't know of her and her sister's existence even when they were in school together. 
After she graduated, she worked as an obliviator in the Ministry of Magic. There were rumours of her practicing dark magic, but there was never evidence to support it nor was there any investigations on it after she had died. 
She married her muggle-born boyfriend of three years Matthew McCarthy and they had two children: Malin McCarthy - a daughter - and Hayden McCarthy - a son. They did however, divorce after seven years and Matthew was given custody of their children, but their children stayed with Alice on weekends and some holidays. Since she was in a minor branch of the Lestrange family, her family did not care for what the blood status of the person she married was. Besides, she was half-blood already anyway. 
In the same year of her divorce, she began dating a half-blood wizard Harry Deighton, who was two years her senior. They dated until her death in 1996. 
Alice died in October of 1996 of an illness. Her funeral was attended by her mother (her father had been dead by the time she died), her sister Isabella, her ex-husband and children, her boyfriend Harry and her school friends Margery Campbell and Beatrice 'Bea' Schwarz. She was buried next to her father. Her mother was later buried beside them.
