Labey Family History
Labey Surname Meaning
As a Channel Islands name and perhaps also as an English name, this is the French surname Labaye, a reduced form of Old French del abbeie meaning ‘of the abbey’. Otherwise, the English name might be a survival of medieval English use of the equivalent Anglo-Norman French name, a variant of Abbey.
Alternatively, the Channel Islands surname and perhaps the English name is the French surname Labbé, a nickname from Old French l'abbe meaning ‘the abbot’. Otherwise, the English name might be a survival of medieval English use of the Anglo-Norman French l'abbé with a fused French definite article.
Compare the Devon example cited under Abbey.
