The high school in Hocus Pocus 2 is named after Samuel Skelton, a real historical figure from Salem, Massachusetts. Skelton was the first pastor of the First Church in Salem, organized August 6, 1629 (via The First Church in Salem, Unitarian). Born in either 1592 or 1593 in Coningsby, Lincolnshire, England, he was a member of the “vanguard” of Puritan settlers in New England who arrived in Salem in 1629 (via Norris Taylor Genealogy Page).
Skelton died five years later, almost six decades before the Salem witch trials took place, so he would not have been present at the events that killed the Sanderson sisters in the “Hocus Pocus” films. However, as the founder of the First Church in Salem, he was certainly responsible for building the ideologies and cultural climate that later led to the witch trials.
