Ronald Bilius "Ron" Weasley is the youngest son of Arthur and Molly Weasley, and a good friend of Harry Potter, who later becomes Harry's brother-in-law due to his marriage to Ron's sister, Ginny.

He comes to marry Hermione Granger, and ends up having two kids: Rose and Hugo. But an unnecessary fact is that in the Harry Potter franchise they are all related due to the House of Black.
