| | Ontario County, New York Genealogical Records Information |
 | | A line drawn due north and south through New York State, touching the west shore of Lake Seneca, will mark the eastern boundary of the original County of Ontario as it was in 1789. |
 | | In December, 1786, a section which included the present counties of Ontario, Steuben, Genesee, Allegany, Niagara, Chautauqua, Monroe, Livingston, Erie, Yates, and the western halves of Orleans and Wayne, were turned over to the State of Massachusetts, subject to the claims of the Seneca Indians. |
 | | In 1821, both Livingston and Monroe were born; in 1823 Ontario gave areas to Yates and Wayne; the boundaries established then are those of the present. |
