Ieuan

Ieuan is the traditional Welsh form of John, itself derived through Latin Iohannes and Greek Ioannes from the Hebrew name Yohanan, meaning God is gracious. It was widely used in medieval Wales and remains a distinctly Welsh marker of the broader John family of names. Several Welsh poets and historical figures bore the name, helping to anchor it in Welsh cultural identity. Related forms include Ifan, Evan, Ioan, and the Anglicized John.
