Just ran across a minor detail about when Molly and Arthur Weasley were
at Hogwarts. When Mrs. Weasley and Bill are strolling around the grounds
prior to the 3rd Tournament Task, Mrs. Weasley tells Harry that they
planted the Whomping Willow AFTER she left Hogwarts, which makes her at
least seven years older than Remus Lupin (and James, Lily and Sirius),
since Lupin says they planted the willow the year he became a student.
