Tetford is listed as "Tesforde" in the Domesday Book, with a mill, probably on the site of the present 17th-century watermill near the centre of the village. The parish contains traces of ancient encampments thought to be from Saxon times. It is reputed to be the site where Raengeires, a Briton, defeated the Saxon general Horsa in a great battle. In 1841 the parish was noted for its fertiliser production made from burnt limestone. The Edward RichardsonCommunity Primary School was founded through a 1714 bequest from Edward Richardson of a cottage and about of land towards teaching the poor children of Tetford and Salmonby. In 1821 a National School was built and enlarged in 1897 and 1899. For many years Tetford was the home of Methodist preacher Charles Richardson, known as the 'Lincolnshire Thrasher'. Richardson was an uneducated farm labourer who late in life discovered a gift for evangelistic preaching and was invited to preach throughout England. He was inspired by a 'time of refreshing' at Tetford starting at Christmas 1826 when a chapel congregation enjoyed a service 'like a little Pentecost' which continued until 3am. After this they went to Mr Riggall's house and 'such a baptism of the Holy Spirit was bestowed upon him as he had never received before.' A biography of Richardson, 'The Peasant Preacher', went through at least four editions. The White Hart Inn, parts of which date from the 16th century, was once the meeting place of the Tetford Club for local gentry, whose members included Tennyson from nearby Somersby. During the 2007 United Kingdom floods the village was affected with East Road and West Road being flooded, causing the north of the village to be cut off from the south.
Village amenities include the Edward Richardson Community Primary School, the White Hart Inn public house, and a doctor's surgery.
Church
A place of worship has stood on the site of the Church of St Mary for over 900 years. The present building erected in the 14th century is built of local greenstone and had a tower added in the 15th century. Outside the north-east of the chancel is a headstone to two gypsies, Tyso Boswell and Edward Hearn, killed by lightning on the eve of Horncastle Fair in 1831. Inside the church is a memorial to Captain Edward Dymoke who was the champion of George II. His helmet and breastplate are above the tablet high on the arch high up to on the right-hand side of the main area of worship. The inscription reads: "To the Memory of Captain Edward Dymoke, cousin of Lewis Dymoke of Scrivelsby. Champion to King George 2nd. Interred March 5th 1749 also John Dymoke Gent, nephew of the above. Interred July 23rd. 1748. Also of Mrs. Jane Dymoke his wife, Interred July 27th. 1745". The church was restored in 1910 and seats about 250.
Tetford and its neighbour Salmonby hold an annual Scarecrow Festival. Households build scarecrows and display them outside their houses during May every year. The scarecrows are modelled on TV and films persons, historic figures, contemporary figures and fictional icons. The Festival is largely dedicated to raising funds for the 14th-century church, however, part of the proceeds of the weekend are shared with other local charitable organisations in the village. The Scarecrow Trail is just over long.
