From the Old French name Héloïse
, which is probably from the Germanic
, composed of the elements heil
"hale, healthy" and wid
"wide". It is sometimes associated with the Greek word ‘ηλιος (helios)
"sun" or the name Louise
, though there is not likely an etymological connection. This name was borne in the 12th century by Saint
Eloise, the wife of the French theologian Peter Abelard. She became a nun after her husband was castrated by her uncle.
There was a medieval English form of this name, Helewis, though it died out after the 13th century. In the 19th century it was revived in the English-speaking world in the form Eloise.
