Hugh Montgomery was a Captain in the British Cavalry and was stationed in North Ireland in the late 1680’s-1700’s. Later, he was promoted to Major. In the book, “Ireland in the Empire, 1688-1770,” on page 61, it says: “Duke of Ormond, Lord Lt. over No. Ireland, for the Crown, immediately after the parliament for 1703-1704 ended it’s Session, left for London, but appointed for his absence, as Lords Justices Sir Richard Cox, Major General Thomas Earle and Hugh Montgomery, Earl of Mount Alexander.” So in 1703, he was made an Earl and given the title of Earl of Mount Alexander.
