Dutch captains: Claes, Marinus, and Dirck Juynbol

Claes and Marinus Claeszoon Juynbol were both convoyers of the Admiralty of Rotterdam (the Maas), who came first to the blockade of the Spanish Armada in the Downs, and took part to the last aaction. They were the sons of Claes Marinuszoon Juynbol, who died in August 1629, and had taken part on the Neptunus (26 guns: 2-24pdr, 16-18pdr, 2-12pdr, and 6-6pdr), under Piet Hein, in the capture of the Spanish Silverfleet. [p.195 from Dr. M.G. De Boer's book, Tromp en de Armada van 1639. The Biographical Dictionary made an error, combining the careers of the elder and younger Claes. Mollema made that same error in the "Honor Roll". Claes (Nicolaes) had distinguished himself under Tromp against the Dunkirkers in 1634, and again at the Downs in 1639. In 1646, as a convoy commander for the Maas, fought against 6 Dunkirkers and preserved the convoy, but was severely wounded. In Rotterdam on 5 January 1647, he was assassinated. Dirck Janszoon Juynbol lived from 1615 until 11 December 1652. He was promoted to captain in 1652. In 1639, he served as a lieutenant at the Battle of the Downs. He distinguished himself at the Battle of the Kentish Knock, and was drowned during the loss of his burning ship at Dungeness. Dirck Juynbol commanded the Rotterdam Directors' ship Gelderland (30 guns and a crew of 131) during the most of 1652. Marinus Juynbol, on 26 February 1652 commanded the ship Schiedam (26 guns), which was one of a group of ships built in 1639 that had dimensions: 116ft x 27ft x 11ft. Dr. Elias says that Dirck Juynbol was his brother and that Dirck was Marinus' lieutenant on the Schiedam on 26 February. He also seems to indicate that Marinus Juynbol was dismissed and command was transferred to his brother Dirck.
