Leonello is an Italian masculine given name, derived from the Italian word 'leone', meaning lion. It translates to 'little lion'. This name was particularly popular in Renaissance Italy, notably borne by Leonello d'Este, the son of Duke Ercole I d'Este and the brother of Isabella d'Este, who lived in the 15th century.
"Leonello saw a rise in popularity between 2020 and 2022, with eight births recorded in the latter year compared to six in the former."
