Guillette

Guillette is a diminutive form of the French name Guillemette, which itself is the feminine form of Guillaume. Guillaume is the French equivalent of William, a name of Germanic origin meaning 'will-helmet' or 'resolute protector'. The suffix '-ette' is a common French diminutive, indicating smallness or endearment. The name would have been used to refer to a 'little William' or 'daughter of William'.

While not as common as its longer forms, Guillette has a charming, old-world French feel. Its usage likely peaked in earlier centuries in French-speaking regions, reflecting the popularity of its root name, William, across Europe. It is now a rare name, often found in historical records or as a surname.
