Hermione Jean Weasley (née Granger), born 19 September, 1979 was the daughter of Muggles Mr. and Mrs. Granger who were both dentists in the Muggle world. She learned, at the age of eleven, that she was a witch and had been accepted into Hogwarts School of Witchcraft and Wizardry. Hermione began attending the school on 1 September 1991, when she was eleven, almost twelve, and was sorted into Gryffindor House.
An academically brilliant student, Hermione became best friends with fellow Gryffindors Harry Potter and Ron Weasley in her first year of school. When they first met on the Hogwarts Express, Ron and Harry thought of her as obnoxious and self-centred, a belief that she only furthered as the school year went on, besting them in every class. However, when Ron and Harry saved her from a troll, she took the blame for them and became their friend. In her second year, Hermione was one of the victims of the basilisk that was unleashed upon Hogwarts with the opening of the Chamber of Secrets, but recovered from being petrified. The next year, Hermione was given permission to use a Time-Turner to facilitate her attending more classes than other students, and which she and Harry later used to save Sirius Black from receiving the Dementor's Kiss, and Buckbeak the Hippogriff from certain death. Hermione became an advocate for the better treatment of house-elves, forming the association S.P.E.W., in her fourth year. In 1995, she was the driving force behind the creation of Dumbledore's Army, and fought in the Battle of the Department of Mysteries in 1996, and in the Battle of the Astronomy Tower and the Battle over Little Whinging in 1997. Hermione, as well as Ron, decided to forgo their last year of school in order to accompany Harry on his quest to find and destroy Lord Voldemort's Horcruxes, and later fought in the Battle of Hogwarts and survived the war.
Second Wizarding War, Hermione went back to Hogwarts to complete her education, and later attained employment at the Ministry of Magic, furthering her cause for the better treatment of house-elves before gaining promotion to the Department of Magical Law Enforcement. She eventually married Ron, and they have two children: a daughter called Rose as well as a son named Hugo. Hermione also became the godmother of Harry and Ginny Potter's eldest son James.
