Lyall Lupin

Lyall Lupin was an Authority on Non-Human Spirituous Apparitions who was responsible for getting rid of the Screaming Bogey of Strathtully, a Boggart that had fed on the fears of local Muggles to the point that it had become an elephantine black shadow with glowing white eyes, by trapping it in a matchbox. .

On an expedition to a remote Welsh woodland to battle a supposedly very fierce Boggart, he met his future wife, Hope Howell, who worked for an insurance company in Cardiff. He got rid of the Boggart for her and then accompanied her home. Eventually, he gathered up the courage to propose, and she accepted, throwing herself into plans for a wedding, topped with a Boggart-shaped cake.

One day when Remus was four years old, Lyall attended a Ministry of Magic hearing for Fenrir Greyback, who was released under the pretence of being a Muggle tramp. However, Lyall had used a number of terrible insults against werewolves, and Greyback brought two accomplices to the Lupin house shortly before Remus's fifth birthday. They attacked the boy, and he became a full-fledged werewolf; Lyall hid the truth from his son.

Etymology

 * "Lyall" may be from a Scottish surname which was derived from the Old Norse given name "Liulfr" (which was derived in part from "úlfr", meaning "wolf"). "Lyall" is also a common surname (most common in America).


 * "Lupin" is derived from "lupus(a)", Latin for "wolf". Lupin thus means "wolf-like" in Latin, and is also the name of a flower. "Canis Lupus" is the scientific name for wolf. To be described as "lupine" means to "resemble a wolf".  This alludes to the  lycanthropy  in the Lupin family.
