The Weasley family tree is hard to follow at the best of times. It connects to the Prewetts on Mrs. Weasley's side and to the Blacks, Longbottoms, and Yaxleys on Mr. Weasley's side. And, by the end of "Harry Potter and the Deathly Hallows," the Weasley family tree includes the Potters, the Grangers, the Delacours, and the Johnsons, to name a few.
At least 12 Weasley grandchildren are born in the years after the Battle of Hogwarts, including Ron and Hermione's children, Rose and Hugo. Ron's only sister Ginny married his best friend Harry and they welcomed James Sirius, Albus Severus, and Lily Luna. His eldest brother Bill also had three children, Victoire, Dominique, and Louis, with his wife, Fleur Delacour. At the end of the "Deathly Hallows" novel, Rowling revealed a blossoming relationship between Victoire and Teddy (the son of Tonks and Remus Lupin), which, as James notes, really makes him part of the family.
Ron's second eldest brother Charlie remained unattached, but his third eldest, Percy, married a witch named Audrey, and they welcomed two daughters, Molly and Lucy. While Fred Weasley tragically died during the Second Wizarding War, he was never forgotten. His twin brother George married their classmate Angelina Johnson, and the couple named their first-born son Fred. They went on to have another child, a daughter named Roxanne. Ron definitely has his work cut out remembering all those birthdays.
