Antonio is of Latin origin, meaning 'priceless' or 'invaluable'. It's a robust and classic name that has been popular throughout history, particularly in Spanish-speaking countries. The name Antonio was borne by several notable figures, such as the Italian Renaissance painter Antonio da Correggio and the Cuban revolutionary leader Antonio Maceo. It also lends itself well to various nicknames like Tony or Toni.
"The name Antonio experienced its peak popularity between the years 1976 to 1987 with consistent high birth numbers, notably reaching 18 births twice in those years. However, it started declining from 1989 onwards, with a significant dip after 1995, and had only five births each in 2003 and 2006."
