Dutch Captain: Jeroen (or Jan?) Adelaar

At the beginning of the First Anglo-Dutch War, Jeroen Adelaar commanded a hired ship, the Middelburg (30 guns and a crew of 100 men). While he was headed to join a convoy to France, his ship was captured. The Middelburg was a suitable warship, so the English employed her during the war. There is some evidence to suppose that Jeroen and Jan Adelaar were the same man. We know that Jeroen Adelaar commanded the Raadhuis van Haarlem in 1658. We also know that Jan Adelaar commanded the Raadhuis van Haarlem at the Battle of Lowestoft and in August 1665. Perhaps he was a relative, but the fact that Jan Adelaar commanded the Zutphen in 1656, on the expedition to Danzig, might be a clue that the overlapping service was for the same man. Sources:
