The Stad Groningen en Ommelanden

I started looking again at what references that I had for the Stad Groningen en Ommelanden, the ship commanded by Joost Bulter that was sunk by gunfire at the Battle of the Gabbard. The list of 23 June 1653 just says that the captain was Joost Bulter and was a ship of the Stad en Lande. A list dated 20 May 1653 includes the ship and says that the Stad Groningen en Ommelanden carried 38 guns and had a crew of 110 men. A list of 26 May says that the captain was Joost Bulter and that the ship was a private ship of Groningen.
