English Captain: John Grimsditch

John Grimsditch served in the Commonwealth navy. I don't believe that the John Grimsditch who was a lieutenant in April of 1685 was the same man. In 1651, he commanded the Alexander prize. From 1657 to 1658, he commanded the Dutch prize Princess Maria. From 1658 to 1659, he commanded the Dutch prize Elias. From 1659 til 1660, he commanded the 4th Rate Elizabeth. Sources:
