A royal grant by James I transferring sovereignty of the Isle of Man from Robert Earl of Salisbury and Thomas Earl of Suffolk to William Earl of Derby, Elizabeth his Countess, and James Stanley Lord Stanley. The document enumerates all rights, privileges, ecclesiastical patronage, feudal incidents, and revenues associated with the island. This is a foundational document predating the 1765 Revestment but essential for understanding the hereditary lordship structure that the Revestment would later alter.
