Hermione Jean Granger(Weasley) born on the 19th of September, was a smart, hardworking, muggle-born student at Hogwarts School of Witchcraft and Wizardry. Hermione was sorted into Gryffindor even though the Sorting Hat also considered Ravenclaw. Hermione was a bit bossy when she first met Harry and Ron on the Hogwarts Express. Harry and Ron didn’t really think Hermione was that friendly, so they just ignored her. Until, when Hermione was attacked by a troll, Harry and Ron saved her and after Hermione tried to act nicer. Since then, Hermione, Harry, and Ron were best friends. Always rule following, Hermione always tried to stop Harry and Ron from getting into big trouble. In their second year at Hogwarts, Hermione was crucial in solving the mystery of the Chamber of Secrets. She realized that since Harry kept on hearing the voice that no one else could hear, the monster might be a snake or a serpent. She found out that the serpent was moving through the pipes to different parts of the school. During their sixth year, she realized her love for Ron, after being jealous when Ron had a girlfriend that wasn’t her. Scoring 11 out of 12 on her O.W.L’s, Hermione was the only one out of the Hogwarts three to redo their last year after the war. When she finished school, she married Ron Weasley and had two kids, Rose Weasley, and Hugo Weasley.
