Alberta was born in 1391, somewhere in the British Isles. If she enrolled at Hogwarts School of Witchcraft and Wizardry, she attended the school from around 1402 to 1409, under Headmistress Phyllida Spore.
In 1430, at the age of thirty-nine, Ms. Toothill took part in the All-England Wizarding Duelling Competition. She made it to the finals, and proved to be an effective duellist when she, against all odds, defeated the expected winner, Samson Wiblin, with a Blasting Curse. Alberta Toothill died in 1483, at the age of ninety-two. By the 1990s, Ms. Toothill was featured on a Chocolate Frog Card, which pictured her cheering after her defeat of Samson Wiblin.
