Friesland captains

I'm pretty much convinced, finally, that the name Captain Belevelt is probably correct. I had long thought it was a corruption of Bruynsvelt. The trouble is that in this list of ships in Witte de With's squadron, prior to the Battle of the Kentish Knock, there was both captains Belevelt and Bruynsvelt. Eimert Smits, the researcher behind what is at De Sneuper website lists Captain Belevelt separately. He estimates that Captain Belevelt commanded a 24-guns ship with a crew of 80 men. I wonder, though, if he might have commanded the old landsschip, Omlandia (1628), which was still in service.
