I have a page that shows Jan Pietersz Deucht een Arm

I received a sharper image of a page that listed ships from 1652, with some guns. The Jeronimus did not have guns, but the striking feature was that the captain was called "Jan Pieterszoon Deucht een Arm" (one arm). That would lead you to believe that his name was Jan Pieterszoon Deucht, with his nickname being "Een Arm", similar to how Cornelis Jol was called "Houtebeen" (wooden leg).
