Släkthistoria för Elcoat
Elcoat Vad efternamn betyder
of uncertain orgin. It looks like a locative name but no suitable place-name has been identified in Scotland or NE England where the surname is principally recorded and neither Hilcott in Gloucs nor Hilcott in Wilts seem likely sources. A similar-looking surname (H)elcote is recorded in medieval Essex and in post-medieval E Anglia. Perhaps this name migrated to NE England by the east coast trade route. The origin of Middle English (H)elcote is unclear but it might be a pet form of the female personal name (H)elen (see Ellen) + the rare hypocoristic suffix -cote. Alternatively since -cock and -cot are commonly interchangeable in medieval and post-medieval surnames Elcoat and Hillcoat could be a variants of Elcock and Hillcock but these names have not been noted in E Anglia NE England or Scotland.
