Alexander Mackenzie, an officer in the East India Company, is claiming to be the nearest male heir of Sir George Mackenzie of Tarbat, who held the titles of Viscount Tarbat, Lord Macleod and Castlehaven, and Earl of Cromarty. Alexander states that he is the great-great-grandson of Alexander Mackenzie, the brother of Sir George. He requests that the jury recognize him as the rightful heir and return his service to the King's Chancery under their seals.
