Described in his own lifetime as a "ridiculous fellow", Conroy has not been the recipient of much recent positive historical opinion. Twentieth-century Historian Christopher Hibbert writes that Conroy was a "good-looking man of insinuating charm, tall, imposing, vain, clever, unscrupulous, plausible and of limitless ambition." For her part, 21st-century Historian Gillian Gill describes Conroy as "a career adventurer, expert manipulator and domestic martinet" who came to England with "small means, some ability and mighty ambition." In 2004, Elizabeth Longford wrote that Conroy "was not the arch-villain Victoria painted, but the victim of his own inordinate ambition."
