- Army officer and office-holder; b. 1753 in New York City, son of James (Jacobus) De Peyster and Sarah Reade; m. 1783 in New York City Catherine Livingston, and they had six children; d. 19 Feb. 1798 at Saint John, New Brunswick.
- Abraham De Peyster is the loyalist’s loyalist. He fits exactly the popular stereotype, although that image is actually true only of a small minority. He was a member of a wealthy, landed, New York family which had a tradition of office-holding and military service under successive administrations, and which was joined by common interest and marriage to similar families, forming the aristocracy of colonial New York.”
