Vega Black II

Vega Walburga Black (born 1962-1990) was an English pure-blood witch and the first daughter and second youngest child of Orion and Walburga Black. As a little girl, Vega was very obedient. She listened and believed everything her parents said to her, including their hatred towards muggles and pure-blood ideologies. People would say that she looked a lot like her grandmother Melania, as a child. She was very fond of both her brothers, Sirius and Regulus. She was oblivious to Sirius's views against their parents and was deeply saddened when he left 12 Grimmauld Place forever. After he left, she had made attempts to write letters to him, but it seemed as if he had forgotten about her and never wrote back. She also had a sister - Carina - but she died when she was only five, so she never got to spend too much time with her anyway. She, like the rest of her siblings, were very close with their grandparents - Arcturus Black III and Melania Black (née Macmillan). They always enjoyed visiting them at Black Manor. 
She attended Hogwarts from 1973-1979 and was sorted into Slytherin House. Her parents were delighted by her sorting as most members of the Black family were sorted into Slytherin. She was a very shy girl and made only a few friends at school. She was close with another Slytherin girl, Amber Nott. She and Amber stayed friends for many years and was one of the only people invited to Vega's funeral. When she was at school, Vega once again attempted to talk with Sirius, but to no avail. During her third year, she gave up all hope and concluded that he probably didn't want to talk to any of his family members again. 
The year she graduated, her brother Regulus died. She was absolutely grief-stricken and therefore started failing some of her exams. She continued studying though, and ended up just passing all her tests at the end of the year. She continued to mourn Regulus throughout her life. Evidence in her diary suggests that even as she got older, she often thought of Regulus and his death. She never 'got over' his death and never recovered from the initial shock of him dying. Sirius leaving and Regulus's death lead her to decide to live a quiet life. 
After she graduated Hogwarts, she got a job working in a little shop in Marylebone in London. She worked there for many years and lived in a small house that she bought after earning some money. She also started to drink more regularly to forget her sorrows. Her parents were extremely disappointed that she had decided to work in a shop with muggles and not find a proper wizarding job. They even considered disowning her, but in the end, they died before they could make a decision. She didn't shed at tear at either of her parents' funerals, but she didn't know why. 
When Vega found out that Sirius and his family moved in after Walburga died, she had thought to visit him and his family, but she had already let go of hope a long time ago. 
In December of 1989, she contracted an illness. After being treated for 10 months, the doctors weren't able to do anything, so there was no choice but for her to die. She wrote out her will. In it, she said that she wanted all her personal belongings to be returned to 12 Grimmauld Place, sell her house and give everything else to charity. She only wanted a couple of people to attend her funeral, and she stated that it was fine if no one wanted to attend. She saw death as a happy thing, that she would get to meet Regulus again. So at 10:43 A.M. in June 1990, Vega Black was officially proclaimed to be dead. Her funeral was attended by Amber, Sirius, his wife Margaret, their children, her grandfather Arcturus Black II and some muggle friends she made during her time working at the bookshop. When Sirius had finally received her letter inviting him to her funeral, he had regretted not replying to her letters before. He made sure that Vega would remembered, and in her honour, he named one of his children after her - Vega Black III.
