Robert Petre, 3rd Baron Petre

Robert Petre, 3rd Baron Petre was educated at Oxford and acceded to the title in 1637 but enjoyed his honours but a short time, and followed his father to the grave in little more than a year. In 1620, he had married Mary (1603–1685), daughter of Anthony Maria Browne, 2nd Viscount Montague. She was a charitable and gallant Royalist and Catholic, once defying a troop of over a hundred Cromwellian / Roundhead / parliamentary soldiers alone, who wished to search Ingatestone Hall. She was a woman destined to have a long and troubled widowhood. Many are the notices in the State Papers about the Petre property in her days until she died in 1685, two years after her son.
