Dutch Captain: Krijn van den Kerckhoven

I have very little information about Krijn van den Kerckhoven. I wonder if his last name is essentially the same as Krijn (or Quirijn van de Kerckhoff and Paulus van den Kerckhoff). Quirijn is probably a variant spelling for Krijn (or Cryn), so if I didn't know that Quirijn van den Kerckhoff had been killed at the Battle of Portland in early 1653, I would have thought that they were one in the same. We do know that Krijn van den Kerckhoven commanded the Rotterdam or Wapen van Rotterdam in the Battle of Lowestoft in June 1665. The Wapen van Rotterdam was probably built in about 1658. It was Aert van Nes's flagship in the Battle of the Sound in 1658, so that was the first time the ship was mentioned in published sources. We also know that the Wapen van Rotterdam was Aert van Nes's flagship in August and September 1665, so perhaps Krijn van den Kerckhoven was his flag captain, although we do not have the information to know for certain.
