Getting oriented in Oldham County
On the map, La Grange anchors the county as its seat, with Crestwood, Goshen, Orchard Grass Hills, and Pewee Valley spread around it. Founded in 1823 and named for William Oldham (1753–1791), American Revolutionary War colonel, the county has land records that reach back a long way, which helps when you trace a title. Census Bureau estimates show 70,183 residents in 2023 and around 187 square miles of land in the county. Much of Oldham County is built out, so the parcel map is busiest with subdivision lots, though rural edges and undeveloped tracts still turn up.

Professional and technical services had the most, followed by construction and health care and social assistance.

Timber tracts in Oldham County change hands for wood value as much as for building, so check the parcel record and the aerial photo together.
