Page 27, beginning of Chapter 6 (Generation No. 6): [17] Aert Theuniszen [6th generation, s/o Anthonis, 5th generation] was born before 1625 in Heicop, Holland. While Aert's birth year has been generally shown as about 1640, Cameron Allen in his treatise on the parentage of Aert in Vol. 36 of The American Genealogist, thinks he was born somewhat earlier. Mr. Allen's opinion is supported by articles in the GENS NOSTRA. In the December 1979 issue of the publication, Aert is reported to have sailed for New Netherland on the ship Beaver in 1652 accompanied by Theunis Gijsbertsz BOGAERT. Both Aert and Theunis are listed as bachelors implying they were at least 21 years old. In addition Aert is reported to be five years older than Theunis. In John Albert Bogart's book on the Bogart family on page 34 he states Tunis (Theunis) was born in 1625 in Heykoop, Holland. Therefore Aert appears to have been born in the early 1620. Because of the uncertainty of his actual year of birth, in this compilation he is shown as having been born prior to 1625. Aert died about 1687 in NY. As noted elsewhere no record has been found his having taken the Oath of Allegience in 1687. Aert's second or middle name, Theuniszen, is also seen in the records as Anthonize. Theuniszen, which when Anglicized is Tony a diminutative form on Anthonize or Anthony. Both Theuniszen and Anthonize appear in the early records. However, Theuniszen appears to be used more frequently than Anthonize and is used exclusively in this compilation to avoid possible confusion....Aert first emigrated to the colonies in 1652. (See pages 337-342 of the December, 1979 isue of GENS NOSTRA.) The year of his emigration is suported by a record where Theunis Gysbertse BOGAERT (he emigrated to the colonies with Aert) took the Oath of Allegience to the Crown in 1687 stating he had been in the New York (New Netherlands) for 35 years. Also supporting his arrival in the colonies around 1652 are Dutch records which show that Aert owned land in Flatbush and was a resident of New Amsterdam in 1655. Other records show that in 1657 he was assessed for Dominie Polhemius' salary; in 1659 he married Breckje (or Brechtje) BERGEN; and, on 3/1/1660 he, and others, petitioned to form the village of Brooklyn....
