Henry Moore, 4th Earl of Drogheda

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.^[2]

Drogheda's father-in-law was the Government electoral manager for the Cornish boroughs and obtained for him a seat at Camelford at the 1722 election.^[2] In 1725, upon the death of his maternal grandfather Viscount Loftus, he inherited the Loftus estate of Monasterevin.^{[citation needed]}

In 1720, he married Hon. Charlotte Boscawen, the daughter of Hugh Boscawen, 1st Viscount Falmouth, on 11 February, by whom he had one daughter, who died in infancy.^[2] His wife died on 3 April 1735 and is buried in the nave of St Mary's Church, Twickenham next to where the poet Alexander Pope was later buried.

Drogheda continued to spend immense sums on racing and other extravagances and died in Dublin on 29 May 1727. He was succeeded by his brother Edward,^[3] who had to sell much of the Moore estates in County Louth to meet Henry's debts of over £180,000;^[2] thenceforth the family made their seat at Monasterevin, where they later built Moore Abbey.^[1]
