O'Dogherty, chief of Inishowen, and foreman of the grand jury which found a bill for treason against the earls of Tyrone and Tyrconnel, was insulted by Sir George Paulet, the governor of Derry.
O'Dogherty rose, Derry was sacked, and Paulet murdered.
On the 27th of June 1576 he and his brother Anthony were entered de societate magistrorum at Gray's Inn, and a few months later he was sent abroad with Sir Amyas Paulet, the English ambassador at Paris.
In April 1585 Sir Amyas Paulet was appointed to the office of which Sadler, accused of careless indulgence, had requested to be relieved; and on Christmas Eve she was removed from the hateful shelter of Tutbury to the castle of Chartley in the same county.
In August the conspirators were netted, and Mary was arrested at the gate of Tixall Park, whither Paulet had taken her under pretence of a hunting party.
