My source for the name of Cornelis Rocusz Fincen's ship is Dr.Ballhausen's book

I was just looking at my unpublished paper, "Dutch Captains", and saw that my source for the name of Cornelis Rocusz Fincen's ship's name is Dr. Ballhausen's book. Dr. Ballhausen wrote that the Zierikzee Directors' ship was named Liefde. This was a ship that carried 34 guns and had a crew of 110 men. Ron van Maanen doesn't list a Zierikzee Directors' ship, so he is of no help in verifying the name.
