Duncan Stuart McLaughlin (born 1818 – ) was the fourth child to be born to white settlers in Jefferson County. He was the son of Andrew McLaughlin who travelled with John Jones and the former Caroline Addington.
McLaughlin was known as a modest man, proud of his Scottish heritage and able to quote Robert Burns at length. He practiced thrift and left a sizable estate to his son, John.
