Kybert Family History
Kybert Surname Meaning
Unexplained. It has the appearance of deriving from a personal name perhaps a reduced form of Old English Cūðbeorht (see Cuthbert) or a hypothetical Old English *Cybbeorht but more early evidence is needed.
A derivation from Middle English kibrit ‘sulphur’ is unlikely.
