Start Your Grant County Research
Grant County sits at a major northern Kentucky crossroads, between Lexington, Louisville, and Cincinnati, which made it a frequent migration corridor for families moving along the Dry Ridge to Lexington Road and the Covington to Lexington Turnpike. Formed in 1820 from Pendleton County, its earliest settlers often appear in Pendleton, Boone, Kenton, and Scott Counties.
The county was named for Col. John Grant, an early Kentucky pioneer and legislator.
Research Highlights
Grant County researchers will find deeds, marriages, probate files, cemeteries, obituary indexes, and church materials represented across the county’s available collections. Because the county was carved from Pendleton County and borders several major early-settlement corridors, families frequently appear in neighboring counties.
Williamstown has served as the county seat since formation. Most record loss has been minimal. Some older volumes may be incomplete due to aging, handling, and typical deterioration, but there is no documented courthouse disaster.
