Biography
Finn was born at home, his parents having decided to do a water birth. Finn's birth was reletively okay and his parents had been ecstatic. His life before attending any kind of school was filled with adventures outside and playful trecks through the forest around his town. The town Finn lived in was pretty small and everyone knew everyone. Finn was sorta friends with all the kids his age and he attended school with those kids.
Finn was pretty smart for his age and always would prove others wrong with anything he could. Finn was born a girl, and at a very young age, he'd expressed that he was a boy. He would always correct people when they called him a girl or used feminine pronouns for him. He'd been fully addressed as a boy by his parents when he turned seven, it having been four years since he'd insisted. Finn had his name changed to 'Finn' and he had been dressing in masculine clothes since. Finn was an only child, his dad being an only child and his mother having a sister.
Finn's dad, James, was a baker and well-loved by the town which he'd grown up in. Diana grew up outside of the town and came from a fully muggle background, same as James. Diana breifly knew of the wizarding world because of her sister being the only witch in her family. Diana was surprised when Finn presented as a wizard and ended up sending him to live with his aunt.
Kory took him in, Finn's entire enviroment changing from a muggle world to the wizard-only town of Hogsmeade. Kory introduced Finn to the wizarding world and he eventually grew used to the magic just before he got his letter from Hogwarts.

First Instance of Magic
When Finn was six years old, the child had accidentally torn most of his stuft animal's ear off. After a small bout of crying he had unknowingly fixed it and Finn was extremely happy.
