Gil is a surname of Portuguese and Spanish origin. It derives from the given name Gil 1, which itself is a Portuguese and Spanish form of Giles. The ultimate root is the Late Latin Aegidius, from Greek αἰγίδιον (aigidion) meaning "young goat."Saint Giles, an 8th-century miracle worker revered as the patron saint of the crippled, popularized the name across Europe. In Iberia, Gil 1 became a standard given name, often bestowed in honor of the saint. As a surname, Gil arose from the patronymic tradition, indicating "son of Gil" or simply referring to someone named Gil.Notable bearers of the surname include Portuguese explorer Gil Eanes, who in 1434 sailed beyond Cape Bojador, a key milestone in the Age of Discovery. In the arts, the surname appears through figures such as Gil de Ferran (racing driver) and Gil Evans (musician). The surname is also common in Brazil due to Portuguese colonization.Related surnames in other cultures include Geelen and Geels (Dutch), Giles (English), Gilson and Gilles (French), and Giehl (German).Meaning: Derived from a given name meaning "young goat"Origin: Portugal and SpainType: Patronymic surnameUsage regions: Portuguese- and Spanish-speaking countries, especially Brazil, Portugal, and Spain
