Frank Longbottom's father

The grandfather of Neville Longbottom was a pure-blood wizard. He died while his grandson was present, thus enabling Neville to see Thestrals years later. He revealed as much to Dolores Umbridge during her time evaluating a Care of Magical Creatures lesson. Neville mentioned that, in 1947, his grandfather put a fanged gerbil into his grandmother's handbag as a joke, and that after this, she kept a mousetrap in herbag at all times.
