Lupin family

Lupin is the surname of a wizarding family, though they have Muggle as well as magical heritage. They are related to the Tonks family, and thus distantly to the Black, Malfoy, and Potter families. The Lupins supported the Order of the Phoenix during the First and Second Wizarding Wars. Members include Remus Lupin, Nymphadora Lupin, Ted Lupin, and Remus' parents, Lyall and Hope Lupin.

Etymology
Lupin is derived from the Latin word lupus, meaning "wolf". Lupin or lupine is also the name of a flower, and the latter is an English adjective meaning "wolflike". This alludes to the lycanthropy in the family.
