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 (Alpha Canis Majoris), which with an apparent magnitude of -1.46 is the brightest star in the night sky.
