Question: Dr. Thomas Walker State Historic Site marks the area where the physician originally from what state settled?
Context: Longfellow-Evangeline State Historic Site, located in St. Martinville, Louisiana, showcases the cultural significance of the Bayou Teche region.  It is the oldest state park site in Louisiana, founded in 1934 as the Longfellow-Evangeline State Commemorative Area. " Evangeline" was Henry Wadsworth Longfellow's enormously popular epic poem about Acadian lovers, who are now figures in local history.  In the town center, the Evangeline Oak is the legendary meeting place of the two lovers, Evangeline and Gabriel.  A statue of Evangeline marks her supposed grave next to St. Martin of Tours Church.  The state historic site commemorates the broader historical setting of the poem in the Acadian and Creole culture of this region of Louisiana. The Robert Toombs House Historic Site is a state historic site at 216 East Robert Toombs Avenue in Washington, Georgia.  It was the home of Robert Toombs (1810–85), who was a pro-Union U.S. representative and U.S. senator, and then a Confederate general and Confederate secretary of state during the American Civil War.  Operated as a state historic site, the 19th-century period historic house museum also features exhibits about the life of Toombs.  The house was declared a National Historic Landmark in 1973. Castle Hill (Virginia) is an historic, privately owned, 600-acre (243 ha) plantation located at the foot of the Southwest Mountains in Albemarle County, Virginia, near Monticello and the city of Charlottesville, and is recognized by the Virginia Landmarks Register and the National Register of Historic Places.  Castle Hill was the beloved home of Dr. Thomas Walker (1715–1794) and his wife, Mildred Thornton Meriwether (widow of Nicholas Meriwether III).  Walker was a close friend and the physician of Peter Jefferson, and later the guardian of young Thomas Jefferson after his father's death. 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.  It is believed to have been inhabited from c. 400-1350.  The site is maintained by the Missouri Department of Natural Resources as a state historic site.  The name "Towosahgy" is an Osage word which means "old town."  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.  The site includes the Beckwith's Fort Archeological Site, added to the National Register of Historic Places in 1969. 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.  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.  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.  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." The Maggie L. Walker National Historic Site is a United States National Historic Landmark and a National Historic Site located at 110½ E. Leigh Street on "Quality Row" in the Jackson Ward neighborhood of Richmond, Virginia.  The site was designated a U.S. National Historic Landmark in 1975.  The National Historic Site was established in 1978 to tell the story of the life and work of Maggie L. Walker (1867-1934), the first woman to serve as president of a bank in the United States.  It was built by George W. Boyd, father of physician, Sarah Garland Boyd Jones.  The historic site protects the restored and originally furnished home of Walker.  Tours of the home are offered by National Park Service rangers. The Castalian Springs Mound State Historic Site (40SU14) (also known as Bledsoe's Lick Mound and Cheskiki Mound) is a Mississippian culture archaeological site located near the small unincorporated community of Castalian Springs in Sumner County, Tennessee.  The site was first excavated in the 1890s and again as recently as the 2005 to 2011 archaeological field school led by Dr. Kevin E. Smith.  A number of important finds have been associated with the site, most particularly several examples of Mississippian stone statuary and the "Castalian Springs shell gorget" held by the National Museum of the American Indian.  The site is owned by the State of Tennessee and is a State Historic Site managed by the Bledsoe's Lick Association for the Tennessee Historical Commission.  The site is not currently open to the public. The T. C. Steele State Historic Site (also called the Theodore Clement Steele House and Studio, and named the House of the Singing Winds by its original owners) is located in rural Brown County, Indiana, one and a half miles south of Belmont, between Bloomington and Nashville, Indiana.  The property was the studio and home of Hoosier Group landscape and portrait artist Theodore Clement Steele (1847–1926) and Selma Neubacher Steele (1870–1945), the artist's second wife.  Shortly before her death in 1945, Selma donated the property on 211 acre of land to the Indiana Department of Conservation (the present-day Indiana Department of Natural Resources) to establish a state historic site in memory of her husband.  The property was listed on the National Register of Historic Places in 1973 as the Theodore Clement Steele House and Studio.  The Indiana Department of Natural Resources operates the historic site, which is open to the public and offers guided tours of the home and studio.

A representative cabin marks the spot of "the first house in Kentucky".  The site was dedicated in 1931.  A replica of the cabin can be toured. 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.
