George Calvert, 1st Baron Baltimore (1580 – 15 April 1632), was an English politician and coloniser.He achieved domestic political success as a member of parliament and later Secretary of State under King James I.He lost much of his political power after his support for a failed marriage alliance between Prince Charles and the Spanish House of Habsburg royal family.Rather than continue in politics, he resigned all of his political offices in 1625 except for his position on the Privy Council and declared his Catholicism publicly.He was created Baron Baltimore in the Peerage of Ireland upon his resignation.Baltimore Manor was located in County Longford, Ireland.Calvert took an interest in the British colonisation of the Americas, at first for commercial reasons and later to create a refuge for persecuted English Catholics.He became the proprietor of Avalon, the first sustained English settlement on the southeastern peninsula on the island of Newfoundland (off the eastern coast of modern Canada).Discouraged by its cold and sometimes inhospitable climate and the sufferings of the settlers, he looked for a more suitable spot further south and sought a new royal charter to settle the region, which would become the state of Maryland.Calvert died five weeks before the new Charter was sealed, leaving the settlement of the Maryland colony to his son Cecil (1605–1675).His second son Leonard Calvert (1606–1647) was the first colonial governor of the Province of Maryland.

Charles Calvert, 3rd Baron Baltimore (August 27, 1637 – February 21, 1715), inherited the colony of Maryland in 1675 upon the death of his father, Cecil Calvert, 2nd Baron Baltimore, (1605–1675).He had been his father's Deputy Governor since 1661 when he arrived in the colony at the age of 24.However, Charles left Maryland for England in 1684 and would never return.The events following the Glorious Revolution in England in 1688 would cost Calvert his title to Maryland; in 1689 the royal charter to the colony was withdrawn, leading to direct rule by the British Crown.Calvert's political problems were largely caused by his Roman Catholic faith which was at odds with the established Church of England.Calvert married four times, outliving three wives, and had at least two children.He died in England in 1715 at the age of 78, his family fortunes much diminished.With his death he passed his title, and his claim to Maryland, to his second son Benedict Leonard Calvert, 4th Baron Baltimore (1679–1715), his eldest son Cecil having died young.However, Benedict Calvert would outlive his father by just two months, and It would fall to Charles' grandson, Charles Calvert, 5th Baron Baltimore, (1699–1751), (who converted to the Anglican faith) to see the family proprietorship in Maryland restored by the king.
