Probably was educated in England and had legal training, for he appeared often as attorney in the county court. A pronounced Royalist, he had no love for Oliver Cromwell and his objection to the succession of Richard Cromwell, 1659/60, when serving as a member of the House of Burgesses from York County, brought about his suspension by Governor Mathews from his office as justice of York County, 7/6/1659. He represented York County in the assembly, 1656, 1659 and 1660, and was sheriff, 1656. The first of Maj. Croshaw’s many patents for land was that for 600 acres in Charles River (York) County, 5/22/1638. In an Act of Assembly, 1/6/1639/40, he was appointed a tobacco viewer for the western side of Queen’s Creek. On 2/27/1649/50 he patented 1350 acres on the south side of York River (which later fell into New Kent Co.) and on 12/10/1651 1000 acres at “Poplar Neck,” across from land of Richard Croshaw.
