Meaning and history
Éloïse comes from Old French Héloïse, probably derived from the Germanic Helewidis, formed from heil, "healthy, whole," and wit, "wide." Despite later associations with Greek helios, "sun," and with Louise, neither is etymologically related. The name was borne by the 12th-century French scholar Héloïse, who secretly married Peter Abelard and later became a nun and abbess after her uncle Fulbert ordered Abelard's castration. Its medieval English form Helewis disappeared after the 13th century, but Eloise was revived in the English-speaking world during the 19th century.
Eloise has made a dramatic comeback. After first appearing in the US records in 1880, it fell to #999 by 2008, before climbing to #49 in 2025. That year also produced its highest recorded birth count, at 4,251.
