Lucilla

Lucilla is a Latin feminine diminutive of Lucia, itself derived from the Roman root lux, meaning light. The name was common in ancient Rome and was borne notably by Lucilla, a second-century daughter of the emperor Marcus Aurelius, who later became the subject of political intrigue. Early Christian tradition also records several saints by this name, contributing to its continued use in medieval Italy. Related forms include Lucia, Lucilla's masculine counterpart Lucillus, and the French variant Lucille.
