The collection includes the personal papers and correspondence of the Bradford King family of Rochester. Among the papers are the diaries of Bradford King, the son of Gideon King who settled near Rochester in 1797. Bradford left this area after his father's death in 1798, but returned many years later. The diaries cover the period from June, 1811 to April, 1874. During some years the entries are scattered or very brief; in others the notes are voluminous. Included in the correspondence are four volumes of letters from Bradford King to his brother Moses King. Also in the collection are the diaries and personal papers of Moses Bradford King, son of Bradford King, who was a prominent Rochester druggist. Moses Bradford King wrote and published a pamphlet which advocated changes in the calendar for the twentieth century. Much of the correspondence consists of letters written between the two daughters of Moses B. King, Ella G. King and Ada M. King. For a time Ella and Ada King operated the King Seminary for Young Ladies and Children in Rochester. When the school closed, Ella King went west and taught in an Indian school in South Dakota. Ada remained in Rochester where she tutored high school and college students. In 1944, at the age of 80, she enrolled for courses at the University of Rochester extension school, becoming the University's oldest co-ed. She died at the age of 100 in 1964.
