Johnatho is of American origin, derived from the Hebrew 'Yochanan', meaning 'God is gracious'. It is a variant spelling of Jonathan, which adds an 'h' and an extra 'o' at the end. The name Johnatho reached its peak popularity in the United States during the 1960s and 1970s, but it has since become less common. It is considered unique and distinctive due to its unconventional spelling.
"In 1989, there were twelve babies named Johnatho."
