Sirius Black (1877 – 1952) was a pure-blood wizard, the eldest son of Phineas Nigellus and Ursula, and brother of Phineas, Cygnus, Belvina and Arcturus, husband of Hesper Gamp, father of Arcturus, Lycoris, and Regulus, and great-grandfather (and namesake) of Sirius Black III.
Behind the scenes
- Based on a statement by Horace Slughorn, Sirius may have been a member of the Slytherin House. That would make him the only Sirius Black who was sorted into Slytherin house; Sirius Black I died before going to Hogwarts and Sirius Black III was sorted into Gryffindor house. However, he attended Hogwarts c. 1888 - 1895, when Slughorn was not Potions teacher.
- Sirius II had the same name as his paternal uncle who died very young.
- Sirius II named his son Arcturus, the same as his brother and his great uncle.
Sirius is the name of the Dog Star, which is very bright.
