A white lias limestone Roman tessera measuring 25.7 millimetres (1.01 in) x 20.18 millimetres (0.79 in) x 17.75 millimetres (0.70 in) and regularly cut on two faces was found in the area, and may be connected with the remains of a Roman villa or farmhouse by St Margaret's Lane. Part of this building was excavated in 1967 and pottery and paving found there are displayed in the Chard Museum. The name of the village comes from the Old English tat and worp meaning 'A cheerful farm'. In 1254, the spelling was Tattewurthe and was a sub-manor of Chard. In 1554 Thatteworh was granted to William Petre as the 'manor and park of Tatworthy' and remained in the family until 1790. Tatworth in 1850s extended to 1,552 acres (6.28 km 2) and had a population of 852.
