Henry Moore, 4th Earl of Drogheda

Henry Moore, 4th Earl of Drogheda (7 October 1700 – 29 May 1727), styled Viscount Moore from 21 May to 7 June 1714, was an Irish peer and rake who briefly served in the Parliament of Great Britain. He inherited his title and estates at the age of 13, when his father and grandfather died in quick succession. Drogheda rapidly became a debauchee, and after squandering large sums, died at the age of 26, leaving his younger brother a heavily encumbered estate.

Early life Moore was the eldest son of Charles Moore, Viscount Moore by his wife Lady Jane Loftus, the daughter of Arthur Loftus, 3rd Viscount Loftus. His father, Charles, was the heir apparent of Henry Hamilton-Moore, 3rd Earl of Drogheda.

Career Sent on the Grand Tour by his guardian, the Dowager Countess of Drogheda, he escaped from his governor in Brussels in June 1717. Proceeding alone to Paris, he returned home when he ran out of money. In 1719, his grandmother obtained a release of responsibility for him from the Lord Chancellor of Ireland, writing that "he exceeds all the youth that ever went before him for wickedness". Drogheda regularly overspent his allowance of £1,500 per year. who had to sell much of the Moore estates in County Louth to meet Henry's debts of over £180,000; thenceforth the family made their seat at Monasterevin, where they later built Moore Abbey.
