Tibbett

Tibbett, also commonly spelled Tibbet, is a surname of English origin. It is considered a diminutive form of the given name Theobald.

Theobald, from which Tibbett is derived, is a Germanic name meaning "bold people" or "courageous people." It is composed of the elements "theud" (people) and "bald" (bold, brave). Over time, Theobald underwent shortening and familiarization, leading to the development of various pet forms and diminutives, including Tibb, Tibbet, and Tibbett.

The surname Tibbett, therefore, signifies "son of Tibb" or "descendant of Theobald." While not an extremely common surname, it can be found in various English-speaking countries, often with slight variations in spelling. The name's presence reflects the historical popularity of the given name Theobald and the common practice of forming surnames based on patronymics (names derived from the father's name).
