Several sources discuss birth/baptism records for Isaac Simonson, for instance here (person (IV) on that page)
These sources state very precisely that he was baptised December 17, 1732 at "the church in New Amsterdam".
I presume this means the reformed Dutch church, but when I look through the year 1732 in "Parents and Witnesses at Baptisms in the Reformed Dutch Church, 1731-1800" on American Ancestors, I see that December 17 is listed but no baptism for Isaac.
Could there be a different church? Or is this volume incomplete? Or...
(Also, were all the baptisms at that church at that time on Wednesdays?)
Edit: okay, here's a supposed bible record that appears to be for the same Isaac:
but gives a birth date of July 12, 1734. But image IMG_1473 in the same series says this was one of a long string of dates written on loose sheets that were placed in the bible, so perhaps less credible. I don't see a 1734 baptism in those Dutch church records either.
