Devvon is of modern American origin, derived from Devon, a county in southwest England. The name Devvon is often associated with its root word 'deven' meaning 'from the deep valley'. It gained popularity in the United States during the late 20th century as parents sought unique and distinctive names for their children.
"Devvon saw a peak in popularity between 1990 and 1991 with eight births each year, but has since declined, with only five births recorded in both 1994 and 2001."
