"Oliver, the youngest son of Etienne, was born in New York City, 16th September 1708; and died in Beverley, Yorkshire, England, 27th November 1785. He was originally a merchant, being a member of the firm founded by his father. He early took an active part in public affairs, and was noted for his decision of character and personal popularity. He represented the city of New York in the Assembly in 1756-60, and served as alderman of the out-ward from 1754 till 1757. He was active in military affairs during the entire French War, and, in 1755, obtained leave from Connecticut to raise men there for service in New York, for which he received the thanks of the Assembly of his own province. In March 1758 he was appointed to the command of the forces then being collected for the expedition against Crown Point, and succeeded in raising the entire New York City regiment within ten days. He was placed at the head of the New York contingent, under General Abercrombie (about 5000 strong), as Colonel-in-Chief. In the attack on Fort Ticonderoga, 8th July 1758, he supported Lord Howe, and was near that officer when he fell mortally wounded. In November of the same year the Assembly of New York again voted him its thanks 'for his great service, and singular care of the troops of the colony while under his command.' In 1760 he was appointed a member of the Provincial Council, retaining his seat until 1776. In 1763 he was made Receiver-General, and in 1773 Colonel-in-Chief of the Southern military district of the province. 'In June 1776,' says the historian Jones, 'he joined General Howe on Staten Island; and, had that officer profited by his honest advice, the American War, I will be bold to say, would have ended in a very different manner to what it did.' In September of that year he raised three regiments of Loyalists, largely at his own expense, of 500 men each, known as 'De Lancey's battalions.' Of these regiments a brigade was formed, and Colonel De Lancey was commissioned Brigadier-General in the Loyalist service. He was assigned to the command of Long Island, where he remained during the war. One of his battalions served in the South with great credit, under his son-in-law, Colonel John Harris Cruger, doing effective service in the defence of Fort Ninety-six against General Greene. In November 1777, his country-seat at Bloomingdale, on the Hudson, was robbed and burned at night by a party of Americans from the water-guard at Tarrytown, his wife and daughters being driven from the house in their night-dresses and compelled to spend the night in the fields, now the Central Park. Having been attainted, and his immense estates in New York and New Jersey confiscated, General De Lancey retired to England, where he resided in Beverley until his death. Of his four daughters, Susanna married Sir William Draper, while Charlotte became the wife of Sir David Dundas, K.C.B., who succeeded the Duke of York as Commander-in-Chief of the British Army."[7]
