Sirius Black I (1845 - 1853) was a pure-blood wizard, possibly the eldest son of Cygnus Black and Ella Max, and the elder brother of Phineas Nigellus, Elladora and Isla. Sirius died when he was only eight years old, for unknown reasons.
Sirius is a name of the brightest star in the night sky. In the Black family there were also Sirius Black II (a nephew of Sirius I, son of Phineas Nigellus) and Sirius III, Walburga's and Orion's son. If Cygnus was his father, Arcturus Black I was his uncle.
Behind the scenesEdit
- Sirius was maybe a son of Cygnus Black I and his wife Ella Max, but if this is true, that means Cygnus was 16 years old when he had Sirius. This is possibly a mathematical mistake. If Cygnus was his father, Arcturus Black I was his uncle. His aunt may have been Misapinoa Blishwick (née Black).
