During the Middle Ages, the surname of Caldeiro was used in Spain. While the patronymic and metronymic surnames, which are derived from the name of the father and mother respectively, are the most common form of a hereditary surname in Spain, occupational surnames also emerged during the late Middle Ages. Spanish names were influenced by the Germanic speakingVisigoths, who conquered Spain from the mid-5th to 8th centuries, and the Arabic and Muslim Moors who conquered the Spanish homeland from the 8th to 12th centuries. Since Spain was periodically dominated by both of these nations in its past, it shared much in common with both the Visigoths and the Muslims in the occupations they described. Many people, such as the Caldeiro family, adopted the name of their occupation as their surname. However, an occupational name did not become a hereditary surname until the office or type of employment became hereditary.
