Maurio is of Latin origin, derived from the Roman family name Mauri which was given to someone of dark complexion. It is a variant of Maurice, meaning 'dark' or 'moorish'. The name has been used throughout history, with notable figures such as Saint Maurus, a 6th-century French monk. In literature, it appears in works like 'Mauricio, el último rey de la Roma antigua', a Spanish historical novel by José María Carretero Suffolk.
"Maurio had its most popular years between 1975 and 1983, with over 10 births each year, peaking at 18 in 1981, 1982, and 1983. However, the name's popularity has since declined, with fewer than 10 births per year after 1986, and often just a handful or even single-digit numbers from the late 1990s onwards."
