History
The area was originally called Carmon. The town was named for the Jarrett family, who farmed the area during the 1800s and were one of the first pioneer families of the United States. In 1771, Abraham Jarrett was granted 2,380 acres of land near the falling branch area to which was used for the production of hogshead barrels mainly used for the transportation of tobacco. In the same year Abraham Jarrett purchased other areas in and around the Jarrettsville area. Abraham Jarrett married Martha Bussey and had 7 children. My Lady's Manor was listed on the National Register of Historic Places in 1978, and includes portions of Jarrettsville.
