TIBBITS
As described in historical dictionaries
An Etymological Dictionary of Family and Christian Names (1857)
Has the same signification as Theobald, of which it is a corruption. Theobald is in the French Theobaud, pronounced Tibbo, whence Tibbauds or Tibbitts. Theobald is derived by Camden from Theod, the people, and bald, brave or bold, that is, powerful or bold over the people. B. Rhenanus derives it from Theos, God, and bald--God's power.
