| If the definition of a monarch is "the person who heads a monarchy:" than neither Maryland nor New York were named after a monarch. During the time Maryland was named after Mary, she was queen consort (contrast this with the Mary of William and Mary who was queen regnant in her time), the monarch in Britain at that time was Charles I. During the time New York was named after Prince James, the Duke of York, the monarch in Britain was King Charles II. |
