was married to his cousin, Lady Elizabeth Louise Mary, the fourth daughter of the Earl of Rathdowne, who has borne him three children, named, respectively, Henry Power Charles Stanley, Frances Mary and Elizabeth Louise Mary Monck.
Lord Monck is descended from a very ancient family, some of the members of which stand forth prominently in the history of England.
The founder of the house was Wm. Le Moyne, who was Lord of the Manor of Petheridge, in Devon, England, in the year 1066, and from whom came, in the reign of Edward the Sixth, John Le Moyne, the ancestor of General George Monck--the restorer of the monarchy in England — who was created Duke of Albemarle by Charles the Second, and rewarded with large grants of land both in England and Ireland.
The Monck family are related by marriage to the Earls of Rathdowne, Beauchamp, Clancarty, the Marquis of Waterford, and other peers of the United Kingdom.
The family seat in Ireland is at Charleville, in the county of Wicklow.
