Christine, born Christine Danielle Albertson, is the 6th child of Danielle and Richard Albertson and also their 5th daughter. She was born and raised in England, as her family had moved from Reykjavík.
She was naturally taught to speak Icelandic as her entire family was Icelandic, however, she did learn English as well. She wasn't really expected to do much while her family was busy doing stuff to their new house. But it did not stop her from helping out every now and then.
She learnt English faster and better than Icelandic, but she mastered both by the time she was 7. Although her older siblings, already in school, still spent some time with her. While out, however, Christine was generally with her twin, Toby. She did grow close to him, but not quite as close.
If anything, Christine grew close to Hazel, and likes to look up to her and her successes. It's not like she doesn't like her other siblings, but she likes Hazel the most. She tried to spend as much time with her as possible.
When alone, Christine found herself sketching and playing chess at the same time. She often thought long before making moves in chess, and usually she considers all possible opposition moves. She liked these long games, as they really got her thinking.
She spent a lot of her childhood, doing this. She never got bored, and claims that it's "better to have a trained and seasoned mind" rather than "one that doesn't know what it exists for". She occasionally spent some of her time doing this with siblings.
As the years went by, it was almost time for Christine to make her mark in Hogwarts. Her siblings have said that it'd be great, but she will never know for herself...
Her first two years weren't all too eventful. First year, however, she managed to get into the Gryffindor Quidditch Team. It was worth it, and at least now, she had a feel for the sport. Second year, she decided to stay out of the team and practice to get better, because next time she tries out, it might stick.
