Delaware County was formed in 1808 from Franklin County. For records made before then, search the parent county:
Part of Delaware 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.
Part of Delaware County lies in the U.S. Military District, federal land set aside to pay Continental Army veterans of the Revolutionary War with bounty land warrants.
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.
