Ouachita County sits along the Ouachita River, and Camden became a significant river port and later a railroad town. The county had a large cotton-farming economy in the antebellum period, with a substantial enslaved population. The early courthouse records from the 1840s document both the planter families who came from older southern states and the land transactions that accompanied cotton agriculture's expansion in this part of south Arkansas.
Ouachita County was the parent county for several later counties in south Arkansas. Nevada County was carved from Ouachita County in 1871. This means that families in the Nevada County area before 1871 would have their records in the Ouachita County courthouse. Researchers tracing south Arkansas families should be aware of these boundary changes when searching the record base.
Note: Ouachita County was formed in 1842 from Union County. Pre-1842 family records for this area are held in the Union County courthouse at El Dorado.
