Lucais is of French origin, derived from the Latin word 'lux', meaning light. It gained prominence during the Middle Ages and was often used by French nobility. The name has a rich history in French literature and culture, notably appearing in works like 'Les Misérables' by Victor Hugo.
"Lucais had a brief moment of popularity with exactly five babies named Lucais born each year between 1998 and 2003, but it has since faded away."
