Cedrella Weasley

Cedrella Astraea Weasley (née Black) (25 April 1917 - ) was a pureblood witch, the second daughter of Arcturus Black II and Lysandra Black (née Yaxley), and the younger sister of Callidora Longbottom (née Black) and of Charis Crouch (née Black). She attended Hogwarts School of Witchcraft and Wizardry from 1 September 1929 to June of 1936, and was sorted into Slytherin House. She became engaged to blood-traitor Septimus Weasley during her final year and married him not long after completing her N.E.W.T.S. Due to this, she was disowned by the majority of her relatives, and burnt off the Black family tapestry. She became the mother of three sons: Uwaine, Bilius, and Arthur Weasley. She is the paternal grandmother of Arthur's seven children.

Early life (1917 - 1928)
Cedrella was one of her many cousins to be born at Black Manor is Tisbury, Wiltshire, England. She was born on 25 April 1917 as the second daughter of Arcturus Black II and Lysandra Black (née Yaxley). Cedrella was a member of the Noble and most Ancient House of Black, a centuries old pure-blood wizarding family that was known to uphold the values of pure-blood supremacy, and to look down upon anyone who didn't share the same beliefs. She had two sisters, Callidora, who was six years older than her, and Charis, who was four years older. Growing up she was close with both of her sisters and loved her father dearly.

Her paternal grandfather was Phineas Nigellus Black I, who was known as one of Hogwarts least favored Headmasters in history. Phineas was a traditional blood purist, who saw muggles, muggle-borns, half-bloods, and blood-traitors as inferior. He died 1925, when Cedrella was only four years old, so she didn't remember him fully. Her paternal grandmother was Ursula Black (née Flint), a member of the House of Flint, another family of the Sacred Twenty-Eight. Ursula died in 1940, when Cedrella was in early adulthood.

Her maternal grandfather was Alcander Yaxley, a very influential aristocrat of the House of Yaxley, another family of the Sacred Twenty-Eight. Her maternal grandmother was a pure-blood witch.

She had three paternal uncles: Sirius Black II, Phineas Black II, and Cygnus Black III, and a paternal aunt, Belvina Burke (née Black). She had three first cousins through Sirius, Arcturus (seventeen years older), Lycoris (fourteen years older), and Regulus (twelve years older). Through her uncle Cygnus, she had four first cousins, Pollux (fifteen years older), Cassiopeia (three years older), Marius (one year older), and Dorea (one year younger). Through her aunt Belvina, she had three first cousins, Auberon (fourteen years older), Eduardus (thirteen years older), and Louvinia (ten years older).

On her mother's side, she had an uncle Octavian, who was married to Emelot Lestrange and had two first cousins, Enyalius, who was sixteen years older than her, and Althaea, who was fourteen years older. Out of all her cousins, she was close with Marius and Dorea, as they were both closest to her in age.

Hogwarts Years (1929-1936)

Cedrella received her Hogwarts letter in the summer of 1929. Before attending, she visited Diagon Alley with her father and older sister Charis and purchased a wand made of willow and unicorn hair. She boarded the Hogwarts express on 1 September 1929. She was sorted into Slytherin House that same night. ]
