Ieuan

Ieuan is the traditional Welsh form of John, ultimately derived from the Hebrew name Yohanan, meaning God is gracious. It was the dominant Welsh rendering of the name throughout the medieval period, widely borne by Welsh poets, clergy, and nobility, including the celebrated fifteenth-century poet Ieuan Deulwyn. The form was later largely supplanted in everyday use by Ifan and Evan, though Ieuan has remained in continuous use and experienced a revival alongside broader interest in Welsh language and heritage. Ioan is a related Welsh variant also used in Wales today.
