Tiburcio is an unusual and distinctive given name of Latin origin, derived from the Roman family name Trebius. It means 'of the tribe' or 'belonging to the tribe,' reflecting its association with ancient Roman tribes. The name Tiburcio was used in medieval Spain, particularly among Spanish nobles during the Middle Ages.
