English Captain: Sir David Murray

Andrew says that David Murray was a knight, so he was Sir David Murray. I was able to confirm that from Powell's book on the Civil War. Sir David Murray commanded the 2nd Rate Constant Reformation in 1642. He was listed as being assigned to the Summer Guard for 1642. Andrew says that the ship carried 40 guns and had a crew of 260 men at that date. Sir David Murray was only in command up to May 1642. He was dismissed from the service in October 1642, as he was a Royalist. Sadly, I have not been able to add much to what Andrew found. Sources:
