Derrick Dey came to New York City from Holland about 1640 as a soldier in the employ of the West India Company and established a mill and ferry at the foot of Dey Street in New York City. He lived on Broadway, at the head of Dey Street.

Derrick's will, dated 5 Dec 1683, was proved 11 Nov 1687. In it, he wrote: "In the name of God, Amen, know all men by these presents, that on the 5 of December, 1683, before me, Wm. Bogardus, Public Notary, in the presence of the under written witnesses. Dirck Jansen Dey, living just without this city, known to me, being sick a bed." Leaves to his wife Geetie Jansen, "all that land which at present lyeth to the south side of the house where the testator is dwelling, stretching to the land of Mr. Olof Stevens Van Cortlandt, and from the highway to the strand, or water side as far as his right is, reserving only an alley of four feet to the south side of the house." The rest of the premises are left one half to his wife, the other half to his children, Teunis and Jannettie. The testator further declares that he has fully satisfied his son Teunis for his mother's share.

Witnesses, Evert Peters, Albert Leenderts Grovas. Proved by the oaths of the witnesses, and Letters of administration granted to the widow Geetie Jansen Dey, July 11, 1693.
