Hi Steve. I am sorry to say that I cannot help you much. I have those books which I once bought because I found that the number of historic sources in the area is somewhat limited. A lot of DTB is missing or has big gaps. Good luck with your research. 

Found these mentions related to Pancraes Cornelisz, father of Cornelis Pancreaszn, the shipper.

In addition to the 1531 records posted in this thread, these appear to be the only references Pancraes Cornelisz in St. Pancras. Pancraes appeared in a 1573 document, recorded in Alkmaar.
