Karolina Maddox

Karolina Marianne Maddox (née Lestrange) (1915-1975) was an English pure-blood witch and was the daughter of Sylvester Lestrange and Marianne Lestrange (née Prewett). She is the youngest of five children and her middle names come from two of her ancestors from her father's side. As a Lestrange, she was taught about the importance of blood purity. At the age of 15, she was betrothed to Kasper Maddox, her future husband. She did end up falling in love with him though. 
Karolina attended Hogwarts from 1925-1931 and was sorted into Hufflepuff House. Initially, her parents were dissatisfied with the house she was sorted into, as the Lestranges were traditionally sorted into Slytherin, but gradually decided accepted it as they loved Karolina very much. Because her parents were disappointed, she promised to get the best grades in her year. She lived up to this promise and got outstanding grades. She was good friends with Cassiopeia Black, Tessa Black and Katie Macmillan. She and Katie were especially good friends and remained good friends for the rest of their lives. 
In 1975, Karolina was found dead in Maddox House. Later investigations suggest she died from an illness that no one was aware of. Her funeral was attended by her family and her school friends.
