Cecil (Cecilius) Calvert 

Second Lord Baltimore
August 8 1605 - Nov 30, 1675

Cecil was the first son and heir of George Calvert.  He was raised a Catholic, attended Trinity College, Oxford, and in 1628, married a Catholic, Ann Arundell (d. 1649).  He inherited the title, Irish estates, and the 10-12 million acres of American land in what became Maryland from his father, and served as the designer and first Lord Proprietor of Maryland from 1632-1675.  He never journeyed to America, but he skillfully preserved his charter rights from enemies over the course of several decades, established Maryland on a sound and prosperous footing to the depletion of his personal fortune, and consistently and innovatively promoted religious toleration for all Christians living in his colony.  His son, Charles (1637-1715), served as Governor of Maryland from 1661-1675 and as second Lord Proprietor and third Lord Baltimore from 1675 -1715.
