Eloisa is the Italian and Spanish form of Eloise, the English form of French Éloïse via Old French Héloïse, via Old English Helewise which ultimately derives from Old German Helewidis, made up of Germanic elements heil (whole, intact; hale, healthy) and wid (wide), though I’ve also seen the second element related to Proto-Germanic *widuz (wood). Personally, I think the wid (wide) meaning makes more sense, the meaning of the name likely given to a child in the hopes of good health.

In 12th century Paris, Héloïse was the name of a young woman from a good family who was well-known for her intelligence and education. Peter Abelard (more commonly known by his surname) came from a noble family, the son of a knight although Abelard chose to become a philosopher, becoming well-known and highly regarded. He eventually became Héloïse’s tutor and eventually the two became lovers, despite the twenty age year gap between them, with Héloïse giving birth to their only child, a son name Astrolabe (named after the astronomical instrument), although there’s very little known about him. When their relationship was discovered, Héloïse’s family became incensed; Abelard was castrated. Héloïse became a nun and Abelard became a monk. As far as I can tell, they never met again afterwards though they wrote letters to each other, some of which still exist today.
