Caitlin Delacour was born in France in April 24, 1980. She was given to her grandparents who lived in Great Britain since the family had two children to take care and the third one would be too much. She was 1 year old when she moved. The grandparents have magical powers and were pure-blood but do not look down to Half-bloods and Muggle-born.
Caitlin is a half-blood witch, since her other side of the family is not a witch or a wizard. She has shiny, long blond hair, blue eyes, and beauty that makes men attracted to her. She is a kind, sweet, and gentle girl who seems to like nature. She usually spends most of her time outside doing outdoor activities in her yard.
During that time, the family always keeps in contact with Caitlin so they won't forget their parents. Caitlin was lonely and sat in her room most of the time. She never was talked to since her grandparents always go out or go to work. She draws artwork and writes some letters to her family to tell them what happen each week.
When Caitlin is 11 years old, a letter from Hogwarts was received on July 1st, 1991. She opens it and she was accepted to Hogwarts School of Witchcraft and Wizardry. After she showed the letters to her grandparents, they took her to Diagon Alley to buy supplies for school. They went to Gringotts Bank in Diagon Alley to take money out from the grandparent's vault to buy supplies for school and money that Caitlin can spend at Hogwarts. After they got some gold galleons, they let Caitlin to get a wand from Ollivanders shop while they brought the remaining supplies required for first years. Caitlin went into the shop and Ollivander appears from the shelves of wands. She was given a wand to test, and it took awhile to get a perfect match. Finally, they have found a perfect match within thirty minutes. Her wand was a fourteen inch, rosewood, and Veela hair.
After getting her wand, she meets with her grandparents. Her grandparents brought books required for First year courses, quills and parchment, required robes and uniforms, and an owl. The owl the grandparents brought is a Barn Owl which was used in the house, since the other one died due to old age. It was kept in the house and went to Caitlin for the weekend so she is able to send messages.
After shopping for supplies, then they have lunch at the Leaky Cauldron. Caitlin overheard about Harry Potter, who lived after Voldemort attempted to kill him. She is a fan of Harry Potter since she read the article in The Daily Prophet about "The boy who lived" against Voldemort. Soon, it was getting late, so Caitlin and her grandparents went home.
End of the summer season was over, and Caitlin packed up all her stuff and her grandparents went to Kings Cross to the Hogwarts Express which was on Platform 9 and 3/4. Caitlin thought that there was no such thing as a platform 9 and ¾. She was ignorant when she went though the portal to the Hogwarts Express. She says goodbye to her grandparents and aboard the Hogwarts Express train.
