Their reasons for leaving England were simple. For the Catholics aboard the Ark and the Dove, it was to escape persecution and being marginalized socially and economically. For Protestants, it was to seek a better life and like their Catholic shipmates, be open to opportunities the New World offered – opportunities that made the risks worthwhile.

George Calvert, a Catholic, was well-regarded by the English court. The King, James I, St. Clement's Island admired Calvert’s diplomatic skills and knighted him, making him Lord Baltimore. To the Protestant King, Calvert’s Catholicism was not significant, although Catholics throughout England and its Empire were constrained from practicing their religion openly. Nevertheless, Calvert resigned his royal posts and asked the King for a land grant in the colonies where he, his family and others seeking religious freedom could settle. James I died but his successor, Charles I, acceded to Calvert’s request, granting him the land “to the true meridian of the first fountains of the River Pattowmeck.” The land would be named for the wife of Charles I, Henrietta Maria.

George Calvert died before he could visit Terra Mariae, or “Mary’s Land.” His son, Cecil, accepted the charter and made plans for the voyage. Each adult going to Maryland would be granted 100 acres, each child, 50. Indentured servants would receive personal supplies and food.
