Cornelis Vanderveer, of Flatbush was not the son of Aris Janse Vanderbilt & Hillitje Hillegonde Vanderbilt
The error is described in (1) Frederick Doren Stone, Laura M. Stone and Harry Macy Jr.,"Jan Aertsen Vanderbilt, His Children and Grandchildren," New York Genealogical and Biographical Record, Vol. 144, No. 4 (Oct. 2013), pp. 254-260, Vol. 145, No. 1 (Jan. 2014), pp. 65-69:

In their accounts of Aris's family, Teunis Bergen and Jean Rand each listed eleven children, but both accounts are incorrect. In addition to being unaware of Aris's youngest child Catalyntje, Bergen and Rand misidentified three other alleged children. Hendrick was actually a grandson (son of Jan). Two others, Cornelis and Catharine, were Vanderveers rather than Vanderbilts:
• The alleged son Cornelis was said to be born 11 January 1697, died 22 January 1782, married Jannetje Wyckoff, and had a daughter Cornelia baptized in Somerville, New Jersey, 15 October 1738. Rand omitted the daughter, whose alleged baptism cannot be found, but she indicated (without citing a source) that the only Jannetje Wyckoff of that generation was said to have married a Cornelis Vanderveer. In fact, a 1937 RECORD article on the Vanderveer family shows a Cornelis Vanderveer of Flatbush who married Jannetje Wyckoff and died 22 January 1782, aged 85 years, 11 days, giving him a calculated birth date of 11 January 1697 - the exact birth and death dates that Bergen gave for Cornelis "Vanderbilt." In his account of the Vanderveers, Bergen omitted this Cornelis, presumably because he had mistakenly made him a Vanderbilt. There is no evidence that Aris Vanderbilt had such a son.
• Bergen gave Aris a supposed daughter Catharine, born 1 March 1713, who married Jacobus Lefferts. Rand noted that in 1713 Aris's wife Hillitje would have been 60, so she suggested that Catharine might have been an "unknown grandchild or adoptee of Aris." The 1937 RECORD article noted above shows that Cornelis and Jannetje (Wyckoff) Vanderveer had a daughter Catharina, born 21 March 1723, who married Jacobus Lefferts. She was buried in Flatbush near her parents as "Catharina VanderVeer Huysvrouw van Jacob Lefferts." Despite the difference in birth dates, this is almost certainly the Catharine mentioned by Bergen. In his Genealogy of the Lefferts Family, on page 51, he has Jacobus Lefferts marrying Catharine Vanderveer, but on page 88 he calls the same Jacobus's wife Catharine Vanderbilt. There is no evidence of a Jacobus Lefferts who married a Catharine Vanderbilt in this time period, or that Aris Vanderbilt had a daughter by that name.
