“ When it was generally known that the viceroy's mistress was the real power behind the viceregal throne, Halifax found his levées deserted, and perhaps he was not sorry. He never disguised his admiration for the enterprising Mary Ann, and if her position was something unconventional, there can be no doubt of the fact that she held the unique record of being the only woman who has directed and controlled the policy of a Viceroy of Ireland. ”
