This is the first collection of records the researcher should turn to in any genealogical investigation in the Buckeye State. Taking the place of pre-1820 census records, this work presents a county-by-county list of Ohio settlers and residents from about 1800 to 1825. Along with the 1801 tax list of the Virginia Military District, it contains the names of taxpayers listed in various county tax rolls, and it also contains lists of original proprietors and settlers (taken from other sources), names of holders of military warrants, voters' lists, householders' lists, occasional lists of Revolutionary soldiers, and lists of resident proprietors. The work is arranged by county, with multiple tax lists arranged chronologically thereunder. There is at least one tax list given for each of the seventy-five counties covered, the combined lists naming about 50,000 taxpayers. Each county tax list is accompanied by a brief history of the county's formation. Researchers should note that tax lists were not available for the following counties: Auglaize, Carroll, Erie, Fulton, Lake, Lucas, Noble, Ottawa, Paulding, Summit, Vinton, and Wyandot. Our reprint combines the original 1971 publication and the 1973 index, both first published by the Ohio Genealogical Society.
