All around the world, Grego (Grego 
, Graeco ) is quite a rare largely masculine, but seldom feminine forename. The forename Grego is characteristic of Latin America and the Caribbean, particularly Bolivia, where it is quite a rare gender-neutral name, the Dominican Republic, where it is quite a rare masculine name, and Guatemala, where it is a rare male name. Not in comparison with a country's population, it is commonest in Philippines, Bolivia, and Indonesia. More prevalently, Grego is the last name as well as the forename.
