Cirilla Lily Snape is the only child born to Lily Evans and Severus Snape on October 31st, 1980. Lily Evans was a childhood friend of Severus's who stood up for him when James bullied him. While James grew to love Lily, she did not return his affections and married her childhood friend once she graduated from Hogwarts. In 1980 she fell pregnant with a daughter and soon gave birth on Halloween. Being named Cirilla, the baby girl thrived. Her father Severus worked as a double agent for the Order of the Phoenix, and after learning that his daughter was part of the prophecy, Severus took his wife and child into hiding. However, Voldemort eventually found the family and killed Lily who was protecting their daughter. He tried to kill Cirilla, but was instead destroyed with Lily's love for Cirilla. Devastated, Severus saw his wife with no trace of his daughter, thinking that Voldemort must have killed her too. In truth a woman who was helping attend to the injuries of those in Godric's Hollow, found the child, and upon seeing her mother's dead body, took the child in and raised her on her own for the next eleven years. Cirilla is a talented witch, able to do magic since she was extremely young, things that confounded her adoptive mother Claire. She is also a talented flyer and became seeker of her quidditch team in her first year. This was unheard of because you usually had to be in a higher year to be on the quidditch team. She is also quite talented in potions due to skills she inherited from her father.
The woman was a muggle neurosurgeon by the name of Claire Hunt, a beautiful redheaded woman who later adopted the child after no one claimed her. While Claire never let Cirilla know she was adopted. However when her Hogwarts letter came in, Claire was confused, thinking it was a practical joke she threw the letter away until a man by the name of Rubeus Hagrid came personally to drop off her letter, proving magic did in fact exist. With Cirilla's mother buying her things, Cirilla managed to board the train and even made two new friends in a girl named Hermione Granger and Ron Weasley. Cirilla was eventually sorted into Gryffindor with her two new friends. When it came time for potions class, Severus could see Lily in the girl who shared the same first name as his daughter. Using his legilimency, Severus saw that the girl's earliest memory was watching his wife die. Knowing that this Cirilla was the same Cirilla he thought had died, Severus was overwhelmed and tried to tell his daughter the truth, however, because Cirilla had never learned that she was adopted, she did not believe him and took off, telling him to leave her alone.
