Logan County was formed in 1818 from Champaign County. For records made before then, search the parent county:
Part of Logan County lies in the Virginia Military District, land Virginia set aside for its Revolutionary War veterans. It was surveyed in irregular metes and bounds, and the first owners' records follow a warrant, entry, survey, and patent trail.
Other parts of the county were federal Congress Lands or smaller special tracts. Where land was sold by the federal government, the first purchase appears as a federal patent.
Titles that covered Logan County, historic and current, with where to search each one. Not every historic title has been digitized — several survive only on microfilm.
