 In 1613 , the King commissioned Calvert to investigate Roman Catholic grievances in Ireland , along with Sir Humphrey <unk> , ( 1555 @-@ 1625 ) , Sir Charles Cornwallis , ( XXX ? <unk> ) and Sir Roger <unk> , ( 1553 @-@ 1616 ) . The commission spent almost four months in Ireland , and its final report , partly drafted by Calvert , concluded that religious conformity should be enforced more strictly in Ireland , Catholic schools be suppressed , and bad priests removed and punished . The King resolved not to <unk> the Parliament of Ireland until the Catholics " shall be better disciplined " . In 1616 , James endowed Calvert with the manor of <unk> <unk> in Yorkshire , which brought him into contact with Sir Thomas Wentworth , 1st Earl of <unk> , ( 1593 @-@ 1641 ) , who became his closest friend and political ally . Calvert was now wealthy enough to buy the " Kiplin Hall " estate in his home parish . ( Today , the University of Maryland operates a research centre there , while the main building is a house museum owned by the Kiplin Hall Trust . ) in his home parish ; and in 1617 , his social status received a further boost when he was knighted , then becoming " Sir George Calvert " .
