Clark County lies along Interstate-70 and the Indiana State Line. It was formed in 1819 from Crawford county and has been the current size since 1830.
Birth and death records have been kept since 1877. Marriage records and land records date to the
formation of the county. Probate Records
date from 1840. Many of these early
records can be found online at FamilySearch.org.
The County Clerk’s office holds the vital and land records. The Circuit Clerk’s office has probate
records. The Courthouse is located at
501 Archer Avenue in Marshall. Many
records have been indexed by the Clark County Genealogical Society and their
library is across the street at 612 Archer Avenue. Since the library is staffed by volunteers,
the hours are limited – check their website at https://clkcogenlib.wixsite.com/clark-co-gen-library.
Another good resource for western Clark County is the Casey
Township library at 307 E. Main St. in Casey.
Some records are at the IRAD depository at Eastern Illinois
University – primarily vital records, and a few school and township records.
