In the Domesday Book of 1086 the manor of Sock Dennis was in the possession of Robert, Count of Mortain.

The place name derives from "Sock", probably an area of marsh or streams, and the family name of the successors of William the Dane, a 12th-century owner.

[1] The family of Dennis was apparently of Danish origin,[2] and was recorded in early Norman charters in French as le Deneys, meaning "The Dane", which was frequently Latinised by scribes as Dacus, being the adjectival form of Dacia, the mediaeval Latin for Denmark, thus "Danish".

There is an area of well-preserved ridge and furrow earthworks over three fields to the east of Sock Dennis.

A doorway, probably of the early 16th century, and perhaps forming part of the fabric of the church, is incorporated in one of the buildings of Sock Dennis farm,[4] which is all that now remains of the village.
