The Reinier Nooms painting of the Aemilia at the Battle of the Downs

The National Maritime Museum, at Greenwich, has a nice search facility for paintings, by painter. They have a pretty large image of the Aemilia at the Battle of the Downs in 1639. I have a book with a larger reproduction, and I believe that shows that the name "Aemilia" (or some spelling of that name) is written on the stern. My question is: do Dutch warships have their name on the stern, or not? I have thought that they only had the illustration on the tafferel, and that was all.
