Question: Dr. Thomas Walker State Historic Site marks the area where the physician originally from what state settled?

<P0-S0> Towosahgy State Historic Site (23MI2), also known as "Beckwith's Fort," is a large Mississippian earthwork mound site with a Woodland period Baytown culture component located in Mississippi County, Missouri. <P0-S1>  It is believed to have been inhabited from c. 400-1350. <P0-S2>  The site is maintained by the Missouri Department of Natural Resources as a state historic site. <P0-S3>  The name "Towosahgy" is an Osage word which means "old town." <P0-S4>  It is not known if members of the historic Osage, who dominated a large area of present-day Missouri at the beginning of encounter with European colonizers, occupied the site. <P0-S5>  The site includes the Beckwith's Fort Archeological Site, added to the National Register of Historic Places in 1969. <SEP> <P1-S0> Dr. Thomas Walker State Historic Site is a park located six miles southeast of Barbourville in Knox County in the U.S. state of Kentucky. <P1-S1>  The land was donated by the American Legion and the people of Barbourville, and marks the area where Kentucky pioneer Thomas Walker, a physician, built his cabin in 1750. <P1-S2>  A representative cabin marks the spot of "the first house in Kentucky". <P1-S3>  The site was dedicated in 1931. <P1-S4>  A replica of the cabin can be toured. <SEP> <P2-S0> Thomas Walker (January 25, 1715 – November 9, 1794) was a distinguished physician and explorer from Virginia; in the mid-18th century, he was part of an expedition to the region beyond the Allegheny Mountains and the unsettled area of British North America. <P2-S1>  Walker and fellow Virginian, Indian agent, explorer for Patrick Henry, legislator of three states, surveyor of KY/VA & TN/NC borders, and later Revolutionary war general, Joseph Martin, were some of the first colonialists to travel in this area. <P2-S2>  Martin's son, Revolutionary War officer Col. William Martin, describes the naming of the area and river in a letter to historian Lyman Draper, <SEP> <P3-S0> Kennessee is a term coined to denote land along the Kentucky - Tennessee state border that historically lay between the Walker Line surveyed by Dr. Thomas Walker and Daniel Smith in 1779-1780 and the true parallel 36 degrees and 30 minutes surveyed by Thomas J. Matthews in July–September 1826. <P3-S1>  The 6-to-12-mile-wide strip of land below the present southern border of Kentucky between the Cumberland Gap and the point where the Tennessee River enters Kentucky was claimed both by Kentucky and Tennessee at the same time. <P3-S2>  Even after the decision was made in 1820 that the land in the strip east of the Tennessee River belonged to Tennessee, Kentucky was given the right to grant the remaining open land to settlers. <P3-S3>  If a person was born in the disputed strip after 1796, when Tennessee's claim to the Walker line as its northern boundary was recognized, and before 1826, when the dispute was settled, they could have been uncertain as to just which state to say they were born in, especially if they owned or squatted on land right on the border, leading some residents to say they lived in "Kennessee."
