Isabeau

Isabeau is a medieval French variant of Isabel, itself a Romance-language adaptation of the Hebrew name Elisheba, meaning God is my oath or God is abundance. The name gained prominence in France largely through Isabeau of Bavaria, the Bavarian-born queen consort of Charles VI of France in the late fourteenth and early fifteenth centuries, whose name became iconic in French historical memory. It shares its deeper roots with Elisabeth, Isabella, and Isabel, all tracing back to the same biblical source through different linguistic pathways.
