Maryland was started as a colony with relative Freedom of Religion, by its Catholic proprietors under Royal Authority, but the majority soon become Anglican, anddisenfranchized the Catholics.
I am aware of the Protestant Reformation of the 1730s, when a Jesuit priest sold himself to one of my ancestors and became property of the manor lord, untouchable under English Common Law. Perhaps those of lesser standing were disenfranchised, but not those who were landed by grant. Thus the disenfranchisement was not as complete as one might assume.
