Sometime after the end of the Second Wizarding War, George married Angelina Johnson, with whom he had a son named Fred, in honour of his late twin, and a daughter named Roxanne.
He and his brother Ron also turned Weasleys' Wizard Wheezes into a huge money spinner.
A born prankster and inventor, George left Hogwarts prior to graduation to become a successful entrepreneur, alongside his twin brother, and opened the joke shop Weasleys' Wizard Wheezes at 93 Diagon Alley.
He was a member of the Order of the Phoenix and fought in the Battle of the Seven Potters and the Battle of Hogwarts; in the latter, Fred died, leaving George devastated.
They pulled the bars off his window and flew him to the Burrow in their father's Ford Anglia.
While at the Burrow George and Fred came to know Harry better as they spent time flying with him.
This does not include quotations that were actually blunders by the people who said them (see, e.g., Wikipedia: Political gaffe).George started his third year in 1991, when his younger brother Ron began his first year, along with Harry Potter, who soon became his best friend.Harry joined the Gryffindor Quidditch team as its Seeker, and became friendly with George and Fred as well.That year, the Chamber of Secrets was opened and frightening messages were written on the castle walls.Rumours were circulating that Harry was responsible for it, since he spoke Parseltongue and thus might be the Heir of Slytherin.Neither George nor Fred took these rumours seriously, they found the whole thing laughable and frequently joked about it.
