Part of a tract of 3,000 acres granted to John Hillyard by William Penn, March 7, 1683. His great-grandson, Charles Hillyard, built this mansion and resided here with his wife, Mary, daughter of William Killen, first Chancellor of Delaware. According to tradition, here culminated Patty Cannon's raid on Dover, vividly portrayed in George Alfred Townsend's historical novel "The Entailed Hat."

Marker can be reached from King's Highway.
