"The earliest record that I have been able to find in this country [USA] about him, is in the New York Colonil Documents, which state that Abraham Pietersen, of Haerlem (Netherlands [sic]), took possession, in 1636, for the Dutch West India Company, of the Island of Quentensis in front of Sloops Bay. In another place it is described as the Island of Queteurs, in front of Sloop Bay and Pequator's River, and in 1664 they speak of the special possession of Abrham Pietersen, of Haerlem, still living, on the Island of Quetenesse, in Narricanese Bay, near Rhode Island, and also of another island near the Pequot River, called by the English: "The Dutchman's Island." In the latter instance he is spoken of, as of Haerlem, owing to his having lived there when he became interest in the first-mentioned island.
In 1638 he was spoken of as the first miller in New Amsterdam; an in important and lucrative position in those days, and he is sometimes mentioned in the records as Abraham Pietersen, Molenaer, or Miller.
In 1641, on August 29th, he was one of the "Twelve Men" whom the commonalty chose and empowered to resolve on everything with the Director-General and Council, and in 1643, on November 3d, he was one of the "Eight Men" who sent a memorial to the States GEneral of Holland, setting forth the distressed state of the colony on account of the Indian outbreaks, and begging for assistance. The "Twelve Men" and the "Eight Men" were the first assemblies on Manhattan Island.
In 1655, owing to the dangerous condition of the times, it was thought best to strengthen the defence of the city, and on October 12th he contributed towards that purpose, and in 1664, on April 19th, he was assessed for soldiers. At this time he lived on the east side of Heeren Street, now Broadway; the third place south of Wall Street, opposit Trinity Church.
In 1657, on April 14th, he was granted the burgher right, and was Lance Corporate of Company Second of the Burgher Corps.
In October, 1664, he and his son, Isaac Abrahamsen (Van Deursen), swore allegiance to the (Dutch) King of England, William the Third. Evidently his education and wealth were equal to his prominence.
The names of himself and wife, Tryntje Melchior Abrahams (Van Deursen), frequently appear in the records of the old Dutch Church in the Fort at New Amsterdam-- the first time in 1640 and the last in 1667, and their names also appear in the list of members for 1649. Their marriage and the births of their elder children either occurred in the Netherlands, or before the church records commenced. [Their marriage record was subsequently found in Haarlem, Netherlands. JSS]
The family were known by the patronymics of Pietersen and Abrahamsen until 1667, when English influences caused them to use their surname [sic] of Van Deursen; Pieter Abrahamsen Van Deursen being the first to do so. Van Deursen is still retained by some of the descendants, but Van Deusen has been the most used, while Van Dusen has also been used, and in the various records the name has appeared in every imaginable spelling.
There is some reason to belive that Abraham Pietersen Van Deursen had two brothers in New Amsterdam --
Cornelius Pietersen, a cadet in the Second Burgher Corps, who married Tryntje Hendricks; she married, secondly, Frederick Lubbertsen, one of the "Twelve Men."
And Hendrick Pietersen, also called Hendrick Pietersen 1,000 bergen, Hendrick Van Duisberg, alias 1,000 berg, and Hendrick Van Dussenburg, Master of the Masons in 1638, who married Geertje Everts, daughter of Evert Pietersen Keteltas.
Possibly Willem Pietersen, who was Lance Corporal in the First Burgher Corps, was another brother.
Abraham and Tryntje were sponsors at the baptism of Cornelius Pieters' son, Hendrick, October 7, 1640, and Endrick Pieters' son, Evert, May 16, 1644.
Their descendants must have retained their patronymics as surnames, and been lost in the crowd of Cornelisens and Hendricksens, for they cannot be traced as Van Deusens.
Adrian Pietersen, of Aitzema, in the Netherlands, who was a director in the Dutch West India Company, in 1632, is thought to have been another brother.
