Letters patent from James I granting the Isle of Man, Castle, Peel, and all associated rights, revenues, and ecclesiastical patronage to William Earl of Derby, Elizabeth his Countess, and James Stanley Lord Stanley. The grant revokes an earlier 21-year lease to the Earl of Salisbury and Earl of Suffolk (1609). This foundational document establishes the Stanley family's lordship of Man and is central to understanding pre-Revestment governance and property relations.
