Context: Carroll Place, also known as Old Carroll Place, is a historic plantation house located near St. George, Dorchester County, South Carolina.  Research completed circa 2012 at the South Carolina Archives in Columbia S.C. shows the house was built circa 1780, and is a plain two-story, Georgian I-house dwelling.  It is sheathed in clapboard single house and rests upon low brick pillars.  It has a hip roofed verandah supported by six wooden posts.  Its builder was likely Thomas Ferguson or David Campbell.

The Dorchester County Historical Society under took an extensive restoration of the Colonial Era Plantation House and when completed, re-designated the house as the Koger-Murray-Carroll house for three of its previous owners who served in the South Carolina General Assembly: Joseph Koger (married the daughter of David Campbell and inherited the house on her death), Soule Murray (purchased the house and land from Joseph Koger), and James Parsons Carroll (purchased the property circa 1850).  James Parsons Carroll also served in the South Carolina Court of Equity as a Chancellor and was a signer of the South Carolina Ordinance of Secession.  Circa 1974 the house was added to the National Historical Register of Places as the "Old Carroll Place" for which it had become known.  The last owner/occupants of the house were the late Fitzhugh Lee Sweatman Sr and his wife Eulalie Knight-Sweatman.  Circa 1970 Mr and Mrs. Sweatman Sr built a smaller one story house off to the side of the Plantation House.  Mr. Sweatman Sr died on the property in 1975.
