Johney is of Hebrew origin, meaning 'God is gracious.' It's a variant spelling of Johnny, which itself is a diminutive of Jonathan. This name was popularized in the United States during the mid-20th century and has since maintained a steady presence.
The name Johney had its peak popularity between the years 1917 and 1926 with 37 births in 1917, 38 births in 1926 being the highest numbers recorded. However, it appears that this name has been on a steady decline since then, with the most recent record showing only 5 births in 2004 and 2006.
