MINOR CHANGES TO THE STORY:
Albus Dumbledore, Fred Weasley and Severus Snape never died.
George Weasley was killed with the Sectumsempra curse shortly before the final duel between Voldemort and Harry Potter.
The Bridgehams: They are the fictional family of My OC, Rosalie (Rose) The youngest (and only surviving) daughter, Lily, married Dennis Creevey and named her first daughter after her dead sister.
Rosalie Bridgeham was a year younger than George Weasley, and the two were romantically involved. She was killed by excessive use of the Cruciatus curse about the same time as the final duel between Voldemort and Harry Potter. She could have survived, but didn't want to live in a world where the future was uncertain.
DISCLAIMER: I DO NOT OWN HARRY POTTER, OR ANY OTHER CHARACTERS, EXEPTING THE BRIDGEHAMS AND AMELIA AND ELIZA WEASLEY. I AM MERLY BORROWING THEM, AND PLACING THEM UNDER THE IMPERIUS CURSE SO THEY DO MY BIDDING.
