Windhams Crossroads, South Carolina is an unincorporated area of land where South Carolina Highway 403 and U.S. Route 401 cross near Lamar in Darlington County, South Carolina named after the Windham surname.  The area is documented in the 1825 Atlas of South Carolina by Robert Mills.  Charles Windham arrived in the colony of Virginia in 1706 on a ship captained by Col. Robert Boiling.  He eventually left to settle in the area of what was then called Craven County, South Carolina where he petitioned and received a royal land grant of 300 acres in 1754 from the Council of King George II of England.  Other land in this area is attributed to Charles' son Amos Windham, who received seven hundred acres in royal land grants between 1769 and 1772.  During the Revolutionary War, Amos Windham served in the South Carolina Militia.  He received his appointment as Lieutenant on February 21, 1776, in the St. David's Parish, and began his service in Colonel G.C. Powell's Regiment.  He served as Captain during 1781, 1782, and 1783 in Colonel Kolb's Regiment, Marion's Brigade, and was commissioned Major after the war ended.  Following the Revolutionary War, Major Amos Windham received thousands of acres in state land grants between 1785 and 1795 in Cheraw District, which was formerly Craven County and later became Darlington County. <SEP>  It existed legally from July 13, 1787, until March 1, 1803, when the southeastern portion of the territory was admitted to the Union as the state of Ohio, and the remainder was reorganized by additional legislative actions. The post-American Revolutionary War Territory Northwest of the River Ohio, more commonly known as the Northwest Territory encompassing most of the pre-war territory of the Ohio Country, parts of Illinois Country, and parts of old French Canada below the Great Lakes was an organized incorporated territory of the United States spanning most or large parts of six eventual U.S. States. <SEP> The Connecticut Company or Connecticut Land Company (e.-1795) was a post-colonial land speculation company formed in the late eighteenth century to survey and encourage settlement in the eastern parts of the newly chartered Connecticut Western Reserve of the former "Ohio Country" and a prized-part of the Northwest Territory)—a post-American Revolutionary period region, that was part of the lands-claims settlement adjudicated by the new United States government regarding the contentious conflicting claims by various Eastern Seaboard states on lands west of the gaps of the Allegheny draining into the Allegheny, Monongahela, and Ohio Rivers. Under the arrangement, all the states gave up their land claims west of the Alleghenies to the Federal government save for parts parceled out to each claimant state.  Western Pennsylvania was Pennsylvania's part, and the Connecticut Western Reserve was the part aportioned to Connecticut's claim.  The specific Connecticut Western Reserve lands were the northeastern part of the greater Mississippi drainage basin lands just west of those defined as part of Pennsylvania's claims settlement (Western Pennsylvania). <SEP>  Darlinton represented Adams County as a member of the Northwest Territory House of Representatives and the Ohio Senate. Joseph Darlinton (July 19, 1765 – August 2, 1851) was an American politician in the U.S. state of Ohio and in the Northwest Territory prior to Ohio statehood.  Darlinton also served as a delegate to the convention that drafted the first state constitution for Ohio.
