 It was built in 1760 by Nathaniel Sands for his cousin Comfort Sands.

 In 2008 the house was donated to the Dorchester County Historical Society by current owners Fitzhugh Lee Sweatman Jr and his wife, Martha Westbury-Sweatman.
 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.

Haphazard is a historic house located on Pleasant Valley Road in Owensboro, Kentucky.
 The house overlooks the Ohio River, and its name is probably derived from the river's eddies.
 The property which Haphazard was built on was originally owned by George Mason, a signatory to the U.S. Constitution, who was given the land in a grant surveyed in 1787.
 Mason's grandson Richard sold the property to Robert Triplett in 1822, by which point the log house forming the central portion of the home had been built.
 Triplett likely added the house's side wings, northern gable, and Federal style interior.
 Triplett accomplished many local firsts, as he was Owensboro's first large real estate dealer; Daviess County's first soil conservationist, barge operator, and author; the first distiller on the Ohio River in the county; and the builder of Kentucky's first railroad.
 In 1843, A. B. Barret purchased the house from Triplett; Barret then sold the house to William Bell the following year.
 Bell, the president of a local bank, likely added the house's Greek Revival portico.
