William Sayre

William Sayre (fl. 1603-1608) was an Irish pure-blood wizard. He was the father of Isolt Sayre, who was one of the founders of Ilvermorny School of Witchcraft and Wizardry.

Life
William was a descendent of Morrigan, an Animagus whose creature form was a crow. By 1603, he had married a pure-blood witch, Rionach Sayre and was living at Ilvermorny Cottage in Coomloughra, County Kerry, Ireland. Their daughter, Isolt Sayre was born that year.

William nicknamed his daughter ‘Morrigan’ for her affinity for all natural things when she was young. He and his wife loved their daughter very much and were quietly helpful to their Muggle neighbours, producing magical cures for humans and livestock alike.

However, when Isolt was five, William and Rionach were killed in a fire made by his estranged sister in law, Gormlaith Gaunt who "saved" Isolt with the intention of raising her with a belief in pure blood superiority. Isolt eventually fled Gormlaith and moved to the New World where she befriended Pukwudgie who she named William in honour of her father. William had two granddaughters through Isolt's marriage to James Steward, Martha and Rionach Steward.
