Benedict Calvert, 4th Baron Baltimore

He was the second son of Charles Calvert, 3rd Baron Baltimore( 1637 – 1715) by Jane Lowe, and became his father's heir upon the death of his elder brother Cecil in 1681.
The 3rd Lord Baltimore was a devout Roman Catholic, and had lost his title to the Province of Maryland shortly after the events of the Glorious Revolution in 1688, which saw the Protestant monarchs William III and Mary II accede to the British throne.
Benedict Calvert would make strenuous attempts to have his family's title to Maryland restored by renouncing Roman Catholicism and joining the Church of England.
In February 1715 Benedict became the 4th Baron Baltimore upon the death of his father, and he immediately petitioned King George I for the restoration of Maryland to his control.
However, before the King could rule on the petition, Baltimore died aged 36, outliving his father by just two months.
Shortly afterwards the King restored the title to Maryland to Calvert's young son Charles Calvert, 5th Baron Baltimore.

He received the proprietorship after the death of his father, George Calvert, 1st Baron Baltimore, (1579 – 15 April 1632), for whom it had been intended.
Cecil Calvert established and managed the Province of Maryland from his home, Kiplin Hall, in North Yorkshire, England.
As an English Roman Catholic, he continued the legacy of his father by promoting religious tolerance in the colony.

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.
