In 1315 Sir John de Wygeton died. At his death he held most of the land in Waverton.

One of the sub-tenants was Robert del Dykes who held an eighth part of Waverton by homage, and 20d. cornage.

Cornage was a tax fixed according to the number of horned cattle pastured.

Unfortunately, there is no further mention of Robert del Dykes and no Inquisition Post Mortem for him as he did not hold his land directly from the crown i.e. was not a tenant-in-chief.
