In researching a New Amsterdam Dutch church's records I found that the most likely emmigrant in the Van Syce family is the father not the son and here is the proof.
I hope you can make sense of this set of details but they add up to me as if our direct Corneliszen Dutch ancestors were in New York by 1630 or in short 4 years after the American Indians left.
Also there appears to have been a brother or cousin,Laurens Corneliszen, of Carel Corneliszen our families first immigrant to New Amsterdam, not his son Joost Carelszen,that we did not to date know about who in 1640 is a witness on March 25 1640 to a Baptism as shown below.
Also if Carel Corneliszen's son Joost Carelszen (Van Sysen), the so called first American ancestor of the Van Sise family, was born in Middleburg, in the Province of Zeeland, the Netherlands, in 1640 he could have NOT have made this statement "according to his statement upon joining the New York Dutch Church, probably about 1630."

Joost Carelszen (Van Sysen), the first American ancestor of the Van Sise family, was born in Middleburg, in the Province of Zeeland, the Netherlands, according to his statement upon joining the New York Dutch Church, probably about 1630. As he first appeared in the New Amsterdam Church Records on 22 Dec 1653, and fairly frequently thereafter, it is possible that he came to New York (New Amsterdam) not long before. Joost was a shipbuilder in partnership with Hendrick Lambertszen Mol, and their shipyard was at "Smith's Valley" on the West Side of the Present Pearl St. between Wall Street and Franklin Square, which had been bought before 17 May 1661. Valentine listed his property in 1674 as of "4th class" and estimated his wealth £10. Joost became a member of the New York Dutch Church on 28 May 1701, when he was recorded as being from Middleburg, Holland. He and his wife were still living in 1703; then over 60 years of age, according to the New York City Census of that year. His wife, Styntie Jans of unknown parentage, he probably married in Holland.
The Van Sises were a small family and it can be stated with soem certainty that all those in America of this name or the alternative Van Cise are probably descended from the same common ancestor [Joost Carszen], particularly since historically there was practically no Dutch Immigration to these shores between 1675 and 1848...
From "The Van Cise Families-Early History", by Jerrold
G. Van Cise.
The New Netherlands Family: The early records of this family, in New Netherlands, are hidden under the patrynomic of "Joost Carlze", our first ancestor in America. He was born in Middleburg, in the province of Zeeland, and immigrated before 1653 to New Netherland (now known as New York). He was a shipbuilder, in partnership with Hendrick Lambertszen Mol; and their yard was built on the west side of what is now Pearl Street, between Wall Street and Franklin Square... The descendants of Joost anglicized their name to Joseph, and gave it to many of their sons. Similarly they anglicized the family name to Van Sise or Van Cise.
According to Colonel Phillip Van Cise, the alternative spelling "Van Cys" had also been used in Holland. Early generations then scattered north to Schenectady, east to Long Island, and south to New Jersey and Pennsylvania.
Our Probable Size descent line is from Carel Corneliszen
