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. Calvert died five weeks before the new Charter was sealed, leaving the settlement of the Maryland colony to his son Cecil.
Cecil Calvert, 2nd Lord of Baltimore, founded Maryland in 1632. Cecil's father, George Calvert, had received a royal charter for the land from King Charles I. The new colony was named after Henrietta Maria, the wife of the king.
Hope this helps!!
