So, where did the Friesland ship Groningen come from?

The bottom line is that I have no definite information about the origins of the Frisian ship Groningen which fought in the Battle of the Sound in 1658 and that was captured by the English in 1665. Clearly, Dr. Weber and Vice-Admiral van Foreest thought that very likely, the Groningen was the ship listed in the Staet van Oorlog te Water for the year 1654 as having been purchased (in 1652?). Dr. Weber used the dimensions of that ship for those of the Groningen in the book about the Four Days' Battle. The Groenewald was a mystery ship, as there is no sign of the ship having served in the First Anglo-Dutch War, despite what Vreugdenhil wrote in his list. The ship Groenewold was ship number 122 in Vreugdenhil's list. The Groenewold is described as entering service in 1652 and last being mentioned in 1655. He gives the dimensions as 132-1/2ft x 31ft x 13ft and says that the Groenewold carried 44 guns. Vreugdenhil shows the Groningen as first appearing in 1658, in time for the Battle of the Sound.
