Gerrit Munth was Willem Ham's lieutenant in April 1652

I was reading copies, this morning, from the Collection Johan de Witt, and looked a page that listed captains and their lieutenants in April 1652 for the Admiralty of the Noorderkwartier. I had seen this before, but had forgotten that in April 1652, Gerrit Munth was Captain Ham's lieutenant. I presume that this meant Willem Ham, who commanded the Noorderkwartier ship Sampson at the beginning of the First Anglo-Dutch War. Fairly early, Gerrit Munth was appointed as captain of the 28-gun ship Huis van Nassau. By May 1653, he commanded the 32-gun ship Lastdrager and did so up to at least November 1653.
