Some colonists were Congregational, Baptist, Presbyterian and Dutch Reformed. Those were Calvinists.
There were also Episcopals, Methodists, Lutherans, Pietists, Quakers, Catholics and Unitarians.
Calvinists made up a majority of the population in Massachusetts, Connecticut and New Hampshire colonies.
They were in the minority in New York (largely Episcopal and Dutch Arminians), Pennsylvania (Episcopal, Quaker, Pietist, Lutheran), New Jersey (Episcopal in the north, Lutheran in the south), Virginia (largely Epsicopal), the Carolinas (Episcopal on the coast, Presbyterian in the upcountry), Maryland (Episcopal, Methodist revival and Catholic), Delaware (Episcopal and Lutheran) and Georgia (Methodist revival, Episcopal, Presbyterian).
