Isabeau

Meaning & origin

Isabeau, a name with medieval French roots, has a distinct and graceful sound that has attracted American parents since the late 20th century. It first appeared in U.S. records in 1987, and peaked in popularity in 2013. Since 2014, however, its usage has been on a slow decline. As of the latest data, about 1 in 267,878 newborn girls receives this name, making it a rare but recognizable choice. Its core meaning, 'pledged to God,' ties it to the long-established family of Elizabeth names, while its French spelling and pronunciation give it an elegant, exotic flair. Despite its rarity, Isabeau has not seen a resurgence in the 2020s, but for parents seeking a name with historical depth and a romantic sound, it remains a compelling selection.

Isabeau is a medieval French variant of Isabelle, itself derived from the Provençal form of Elizabeth. The name Elizabeth comes from the Hebrew Elisheva, meaning 'God is my oath' or 'pledged to God.' Isabeau was used in medieval France and appears in historical records, including Queen Isabeau of Bavaria, consort of Charles VI. The name saw a revival in the late 20th century, particularly in English-speaking countries.
