Under authority of a letter from the home government addressed to Nicholson "or in his absence, to such as for the time being takes care for preserving the peace and administering the laws in His Majesty's province of New York," Leisler had assumed the title of lieutenant-governor in December 1689. He dissolved the committee of safety, appointed a council, and took charge of the government of the entire province. He appointed Jacob Milborne as Clerk to the Council, Attorney-General, Advocate General and his Secretary. Milborne married Leisler's daughter Mary.
