Searching for Records in Genesee County, NY


Genesee County is located in Western New York. The county is bordered by Orleans County in the North, Monroe and Livingston Counties in the East, Wyoming County in the South, and Niagara and Erie Counties in the West.

The county derives its name from a Seneca Indian word meaning “the Beautiful Valley,” an apt description of the county’s splendor. The southern portion of the county includes a range of hills, which transform into low waves as one heads north. As of the 2010 U.S. federal census, the county had a population of 60,079, and encompasses 500 square miles of land. The county seat is Batavia.

Genesee County is also home to many local resources and repositories. The Le Roy Historical Society, for instance, has a genealogical library containing files and archives.  (Le Roy is also the birthplace of Jell-O! While you’re there you can learn about the story of Jell-O, which was invented in Le Roy in 1897.)
