The surname Andrade has its roots in the Galician region, emerging in the twelfth century as the family name of the knights and lords from the small parish of San Martiño de Andrade, located in the municipality of Pontedeume. This area is historically significant, with its first documentation traced back to the ninth century, linked to the monastery of San Xoán de Caaveiro, situated eighteen kilometers away. The region of Pruzos, which included Andrade, was established as an administrative and ecclesiastical territory of the Kingdom of Galicia in the sixth century by King Teodomiro, through a Latin document known as Parrochiale suevum.
By the twelfth century, Andrade became part of the county of Trastámara, associated with the powerful Traba lineage. During this period, the Fortúnez family began to adopt Andrade as their surname, reflecting their roots in the parish. The knights of Andrade were known for their loyalty as vassals to the Counts of Trastámara throughout the medieval era, solidifying their status within the region.
In addition to its Galician origins, there is a notable Jewish branch of the Andrade surname that originated in Portugal during the seventeenth century, known as da Costa d'Andrade. This branch later migrated to England, further spreading the name's influence. Today, the surname Andrade is predominantly found in Portugal and Spain, as well as in various Latin American countries, Italy, Equatorial Guinea, East Timor, the Philippines, and regions in India such as Goa and Karnataka.
In the United States, there is a significant concentration of Andrade families, particularly in states like California, Massachusetts, Hawaii, and Rhode Island. The legacy of the Andrade surname continues to thrive across the globe, reflecting a rich history intertwined with nobility and migration.
