A lot of the New World colonies of England and later Britain began as massive land grants and colonisation rights given to individuals or groups of individuals as proprietors. Would it be possible for these people to become established nobility of these regions. For example, Cæcilius Calvert was the proprietor of Maryland; he could become Duke of Maryland or similar. William Penn could be the Duke of Pennsylvania also.
Would this be at all possible, and if so, what effect would it have on the American Revolution? Does the United States become a more aristocratic society, or even a full-blown monarchy?
