There is a microfilm tape that you can rent from the LDS Family History Library that is entitled: Vital records of Onondaga County and other localities in the state of New York, 1799-1913 / collected, arranged, typed, and indexed for the New York Genealogical and Biographical Society by Lester Card. It was filmed in 1941. It includes indexes, cemetery, church, and probate records from Onondaga Co and other cos. - Cortland, Madison, Ontario, Oneida, Otsego and Oswego. Call Number: US/CAN Film Area 0017837 item 2-7 The tape was difficult to read, faded, and wasn't very useful in my search for family. However, someone else might have more success with their research. best regards, laurie ackels
