Isabeau is in Origin.
A medieval French form of Isabel, Isabeau descends from Hebrew Elisheva via Greek/Latin Elisabeth and Old French Isabel/Isabelle. The name carries the traditional meaning “God is my oath” or “pledged to God.” Despite the ending, the -beau element is not related to the French word for “beautiful”; it reflects medieval phonetic and scribal variation, also seen in spellings like Ysabeau.
Isabeau flourished in late medieval France and is closely associated with Queen Isabeau of Bavaria (c.1370–1435), consort of Charles VI. The form waned thereafter, surviving in records and literature before a modest modern revival through historical fiction and the film Ladyhawke. Related international variants include Isabel and Isabella (Spanish/Italian), Isabelle (French), Isobel (Scottish), and Isibéal (Irish). Short forms range from Isa and Izzy to Beau. Rare and romantic today, Isabeau offers a distinctive medieval twist on the enduring Elizabeth/Isabel family.
