Have a look here at the link below detailing the history of the village.

The author of the site states;

Inside the church are a number of imposing 18th century monuments to the Jemmett and Raymond families, featuring busts of the deceased. Phillip Jemmett, a London brewer, purchased the mansion of Barton Court in 1665 and his descendants, the Raymond and Dundas families, including Lord Amesbury, lived there until 1832.

Barton Court was one of the nine manors into which the parish is divided. Seven of them are mentioned in the Domesday Survey.

There is also this information,I ahve found:

It is situated on the river Kennet, and the Kennet and Avon canal passes through the parish. It was anciently called Kennetbury, and was formerly a market town and had two fairs. It contains the townships of Holt and Denford. Many of the inhabitants are employed in the silk mills. The parish, which is considerable, has a large tract of common. Many Saxon coins of the reign of Edwy were found here in 1762. The impropriate tithes have been commuted for a rent-charge of £402, and the vicarial for £803.
