Eloy

Eloy is the Spanish form of Eligius, a Latin name associated with being chosen. It belongs to the same family as French Éloi, Catalan Eloi, and Italian Eligio. The different endings and accent marks reflect the languages in which these forms developed, while their shared history leads back to the same older name.

Saint Eligius gives Eloy a long Christian connection. He was a seventh-century goldsmith who became bishop of Noyon, and his reputation linked him especially with metalworkers. That combination of skilled craftsmanship and religious history is a more specific association than the meaning alone. Eloy is therefore an established short name with a substantial background, rather than simply an abbreviated form of a longer modern El-name.
