The De Lancey family is one of Huguenot origin, the founder of the family,[3] Etienne De Lancey, having fled from France at the time of the Revocation of the Edict of Nantes in 1685.
[3] In French annals the family can be traced back to the time of the Hundred Years' War. The first of the name, of whom there is any authentic record, was Guy de Lancy, Vicomte de Laval et de Nouvion, who in 1432 held of the Prince Bishop of Laon and Nouvion, villages and territories a few miles south of that city. See History of New York during the Revolutionary War, by Thomas Jones, edited by Edward Floyd De Lancey, vol i., p. 651, and Dictionnaire de la Noblesse de France, vol. viii., title "Lancy."
The following extracts treating of the family history are taken from Appleton's Cyclopædia of American Biography.
The author of the articles, Edward Floyd De Lancey,[4] was born in 1821, and died at Ossining, N.Y., on the 7th April 1905. At one time he held the position of President of the New York Genealogical Society, and has done a great deal of work in the field of historical research.

"Etienne De Lancey (great-grandfather of Sir William De Lancey), was born in Caen, France, 24th October 1663; and died in the city of New York, 18th November 1741. Having been compelled, as a Protestant, to leave France on the revocation of the Edict of Nantes (18th October 1685), he escaped into Holland. Deciding to become a British subject and to emigrate to America, he crossed to England and took the oath of allegiance to James II. He landed in New York, 7th June 1686. His mother had given him, on his departure from Caen, a portion of the family jewels. He sold them for £300, became a merchant, and amassed a fortune of £100,000. He married Anne, second daughter of Stephanus van Cortlandt, 23rd January 1700. He took a prominent part in public affairs, representing the fourth ward of New York as alderman in 1691-93, and was a member of Assembly for twenty-four years. While sitting in the latter body he gave his salary, during one session, to purchase the first town-clock erected in New York; and with the aid of his partner imported and presented to the city the first fire-engine that had been brought into the province. The De Lancey house, built by Etienne in 1700 upon a piece of land given to him by his father-in-law, is now the oldest building in the city of New York."[5] Mr De Lancey was buried in the family vault in Trinity Church, New York.
