Major Error in 1820 Census for Onondaga County

For all you people with Upstate New York ancestors this is an important announcement.  There apparently is a major error in the 1820 U.S Federal Census microfilm for the towns of Cicero, Lysander and Manlius.

The following press release was just received:

Press release:

“For Immediate Release

1820 US Federal Census Microfilm Errors Corrected for Onondaga County, NY.

The American Pomeroy Historic Genealogical Association (APHGA)
identified an error in the pagination sequence of the microfilmed copies of the 1820 US Federal Census.  These errors relate to the towns of Manlius, Cicero and Lysander in Onondaga County, New York, and were discovered while attempting to verify the location of the Spencer Pomeroy and Lucy Pomeroy households.

The APHGA’s research indicated that both of these Pomeroy families should have been living in Manlius, N.Y., but both the and Heritage Quest indices placed these households in neighboring Cicero.  By examining the total counts by page and town for both the Manlius and Cicero microfilm rolls on we were able to determine that these pages were filmed out of sequence.  When the pages were sorted out we were able to verify that only 3 pages of the 21 page Cicero microfilm roll were part of the original 1820 Cicero census!

The APHGA has created corrected indices of the 1820 US Federal Census for the towns of Cicero, Manlius and Lysander in Onondaga County for use with and Heritage Quest images.  These indices, along with other documentation explaining how this error was detected and how corrected results were substantiated are available free of charge on the APHGA website at .

The American Pomeroy Historic Genealogical Association was founded by Bill Pomeroy of Syracuse, NY, in order to provide an organization to facilitate American Pomeroy research.  We provide a platform for the collection, communication and collaboration of research regarding the descendants of Eltweed Pomeroy, and act as a clearinghouse for that research.  Bill’s dream is to publish an update of the Albert A. Pomeroy genealogy books, The History and Genealogy of the Pomeroy Family, Volumes I-III, published in 1912 and 1922.  The APHGA has also founded the Pomeroy Anvil Trail, a project to install monuments in the shape of the Pomeroy Anvil across the United States in places that were historic to the Pomeroy Family.

Please feel free to contact us by e-mail at or by phone at 1-800-767-3282 x2530.  For more information about the APHGA please visit our website at .”


That sounds like a very important discovery and we send kudos and thanks for the sharp eye of Nancy Maliwesky, Director, American Pomeroy Historic Genealogical Association and Bill Pomeroy who so tirelessly and benevolently makes this all possible.

If you have a POMEROY anywhere in your family history you will certainly find a treasure trove of information on their website.

Oh, and for what it is worth, the Federal Government in their infinite wisdom discarded all of those original manuscript census enumeration books after they were microfilmed.  Certainly no one would ever need to look at the original documents.
