Tett Family History
Tett Surname Meaning
From the Middle English personal name Tette, either a female name (Old English Tette) or a male name (an Old English *Tetta equivalent to the female Tette which is not on independent record but may be safely inferred from place-name evidence).
Both these names are of unknown origin.
Probably an occasional variant of Tait.
