Henry County is a county located in the U.S. state of Kentucky bordering the Kentucky River. As of the 2010 census, the population was 15,416. Its county seat is New Castle. The county was founded in 1798 from portions of Shelby County. It was named for the statesman and governor of Virginia Patrick Henry.
Henry County is included in the Louisville/Jefferson County, KY-IN Metropolitan Statistical Area. Since the 1990s, it has become an increasingly important exurb, especially as land prices have become higher in neighboring Oldham County.
With regard to the sale of alcohol, it is classified as a moist county— a county in which alcohol sales are prohibited (a dry county), but containing a "wet" city. The town of Eminence allows package alcohol sales.
Many people born in Henry County in the 1820s ended up living in Trimble or Oldham Counties as those counties were created in few years later. “Trimble County was established by the Kentucky General Assembly in December, 1836. Oldham County was established in 1823 from parts of Henry, Jefferson, and Shelby Counties.”
