Jonathon is of Hebrew origin, meaning 'gift from God'. It was quite popular during the Middle Ages but declined in usage in the following centuries. However, it has seen a resurgence since the mid-20th century and is now considered classic yet timeless.
"The name Jonathon peaked in popularity between 1982 and 1988 with a high of 21 births in both 1984 and 1986. However, it has since declined, with only 7 births recorded in the most recent year available (2004)."
