First Families Pioneers
These are lists of First Families Pioneers who are shown in the Warren County Genealogical Society records. These people have been thoroughly researched by a descendant of the listed ancestor which proves their relationship to the individual and documentation that shows the indicated pioneer ancestor was in Warren County, Ohio, before January 1, 1821. This is not a comprehensive list of every person who may have been in the county by that date, only a list of people who have been researched and submitted. If you have an ancestor who was in Warren County before January 1, 1821, and would like their name to be added to this list, please submit an application as described on the First Families main page.
You may also want to check the Ohio Genealogical Society website for information about the First Families of Ohio. It is possible your ancestor has already been proven for that organization. They have updated their First Family Ancestor lists through 2025 and made them available online. https://www.ogs.org/about/lineage/ffo/
