Melania Black

Melania Joanna Black (née Macmillan) (born 1903-1983) was an English (with her mother being Dutch) pure-blood witch and was the only daughter and last child of George Macmillan and Joanna Macmillan (née De Klerk). Ever since she was a little girl, Melania has always been extremely kind to everyone. She was also very disciplined and had a strong sense of duty. Even though her brother Theodore was many years older than her, she still had a strong bond with him and they were each other's best friend. 
Melania attended Hogwarts between 1912 and 1919, where she was sorted into Hufflepuff House - the house where members of the Macmillan family were traditionally sorted into. Throughout her years at Hogwarts, Melania was always a top student. She excelled in all her subjects and later became prefect then Head Girl for her house. On her sixteenth birthday, her parents announced to her that they had secured an arranged marriage for her with the heir to House Black - Arcturus Black III. Melania knew Arcturus from school, but they never really talked to each other. Although Melania didn't like the idea of marrying something she didn't know, she knew that it was her duty to do so and accepted what was planned out for her. After she found out about their betrothal, Melania decided to write Arcturus a letter asking for them to meet during a time when they were both free at school. Arcturus gave Melania a gift - a necklace that his mother owned - which she then wore for the rest of her life. 
After the initial first discussion, the two kept exchanging letters and talking during free periods. Melania also started spending time with Arcturus's friends along with her own. Melania and Arcturus became good friends, that quickly blossomed into love. By the time of their graduation, they were deeply in love with each other. Together, they had two children - Orion Black and Lucretia Prewett (née Black). 
When Melania died in 1983, Arcturus was extremely heartbroken and he would visit her grave often. After he died in 1991, he was buried next to her at Black Manor.
