Gondoline Oliphant

Gondoline Oliphant (1720-1799) was a witch made famous for studying the life and habits of trolls. In 1799, she was clubbed to death in the Cotswolds while sketching.

There was a bust of her at Hogwarts Castle, on a secret passage leading from the fourth floor to the second floor.

Etymology

 * The surname Oliphant is derived from an archaic English word for "elephant." J.R.R. Tolkien included huge, elephant-like creatures known as oliphaunts in his novel The Lord of the Rings.
 * The name Gondoline is perhaps a further nod to Tolkien: in the Silmarillion, there was an Elven city called Gondolin, which remained hidden for centuries before being destroyed.
