Cygnus Black (1889 – 1943) was the fourth son and second youngest child of Phineas Nigellus Black and Ursula Flint, the brother of Sirius, Phineas, Arcturus and Belvina, the husband of Violetta Bulstrode and the father of Pollux, Cassiopeia, Marius, and Dorea.
Behind the scenesEdit
- Based on a statement by Horace Slughorn, Cygnus may have been a member of the Slytherin House. However, he attended Hogwarts c. 1900 - 1907, when Slughorn wasn´t Potions teacher.
- On the film version of the Black family tree, there was no picture of Cygnus, only his and his wife's names. This is corrected on the family tree visible on the DVD2 of the film version of Harry Potter and the Order of the Phoenix
- Cygnus was possibly named after Cygnus Black I, an early member of the House of Black, who was his possible grandfather. His grandson was also named Cygnus.
- It is worth noting that Phineas Nigellus Black (Cygnus's father) was forty-two years old when he had Cygnus. Most House of Black members have their children at considerably young ages, e.g. Pollux Black was thirteen when he had his daughter. It is likely that both of these issues are mathematical errors by J. K. Rowling, for there are many errors in the family tree and Rowling has also admitted that "math is not her strong suit."
- If Dorea (Cygnus's second daughter) is James Potter's mother and Harry Potter's paternal grandmother, Cygnus is James's (maternal) grandfather and Harry's (paternal) great-grandfather.
Like many other members of the House of Black, Cygnus is named after a constellation. Cygnus is a northern constellation also known as the Swan or the Northern Cross. It was named for several swans which appear in Greek mythology, including the one Zeus transformed into to seduce Leda, the form Orpheus took after his death, and a son of the god Apollo who was turned into a swan after his murder. The name is derived from the Greek κύκνος, kyknos, meaning "swan".
