Galo is of Spanish and Italian origin, derived from the Latin word 'gallus', meaning 'rooster'. It was traditionally given to children born around the time of Christmas, as in some cultures, a rooster was believed to announce the birth of Jesus Christ. In Spanish-speaking countries, Galo is often associated with intelligence and wisdom, reflecting the qualities of the bird it signifies. In Italy, it has been used since the Middle Ages and has a long history of use among the nobility. Today, Galo is still used in both Spain and Italy, though it remains relatively rare outside of these countries.
The name Galo has experienced variable popularity over the years, with peaks of 14 births in 1972 and 13 births in 2008, but consistently low numbers since the mid-1980s.
