The Colonial families of Maryland were the leading families in the Province of Maryland. Several also had interests in the Colony of Virginia, and the two are sometimes referred to as the Chesapeake Colonies. Many of the early settlers came from the West Midlands in England, although the Maryland families were composed of a variety of European nationalities, e.g. French, Irish, Welsh, Scottish, Swedish, in addition to English.
Maryland was uniquely created as a colony for Catholic aristocracy and gentry, but Anglicanism eventually came to dominate, partly through influence from neighboring Virginia.
Charles I of England granted the province palatinate status under Cecilius Calvert, 2nd Baron Baltimore. The foundational charter created an aristocracy of lords of the manor for Maryland.
The first areas of colonization were on the Patuxent River and up along the Chesapeake Bay near and around current St. Mary's and Charles counties.
