Belvina Ursula Burke, née Black (1886-1962) was the only daughter of Phineas Nigellus Black and Ursula Flint and the sister of Sirius, Phineas, Arcturus and Cygnus. She was a Healer at Saint Mungo's Hospital, before marrying Herbert Burke.
Belvina was born and raised in Hogsmeade, as her parents were Headmastar and School Nurse at Hogwarts. Belvina was sorted into Hufflepuff House in 1897 and ended her education at Hogwarts in 1904. She started working at Saint Mungo's in 1908 and married her boyfriend Herbert three years after, pleasing her family very much.
Belvina gave birth to three children: Nigellus (1913), Leopold (1914) and Grace (1917). She died of natural causes in 1962.
Belvina was considered quite a beautiful witch that resembled her father and had her mothers eyes that always seemed "lusty".
Although prejudiced against muggle-borns and muggles, Belvina was a very accepting and loving mother.
- She and her great-great-great-nephew Sirius Black III would be the only known Black's not to be sorted into Slytherin House while at Hogwarts.
