Patronymica Britannica (1860)
,'COTT. COT. COTE. A common termination of local surnames, as in Walcott, Caldecott, Norcot, Northcote, Southcote, &c. It appears to be the A- Sax c6te. Professor Leo observes that, " a seiche the dwelling of the wealthy — of landowners, cote on the other hand indicates the abode of the poorer classes. Cote is the house of an indigent dependent countryman, who, without any personal estate, holds a transferable tenement in fief. It was originally a house of mud, or of earth, with loam walls." The prefixed word sometimes indicates the owner's name, and is sometimes descriptive of the situation.
