Johnaton is an uncommon yet distinctive given name of Latin origin, derived from the Roman family name Junius. It is composed of 'Jo(h)n', meaning 'God is gracious' in Hebrew, and 'Aton', a variant of Aeton, which was used by the ancient Romans to denote someone from Atella, a town in southern Italy. The name Johnaton thus signifies that its bearer is a gift or blessing from God, with ties to the land of Atella.
"Johnaton appears to have had its peak popularity between 1982 and 1993, with over 10 births each year during this period. The name's usage has since declined, with fewer than 7 births per year after 2005."
