Meaning
What does Ieuan mean?
The name Ieuan has its origins in the Welsh language and culture, tracing back to the Middle Ages. It is a Welsh form of the name John, derived from the Hebrew name Yochanan, meaning "Yahweh is gracious." The earliest known spelling of the name was Ieuan, which later evolved into other variations such as Evan and Ivan.
In Welsh history, the name Ieuan was associated with several notable figures. One of the earliest recorded instances was Ieuan ap Rhydderch, a Welsh nobleman who lived in the 12th century and was known for his bravery in battles against the Normans. Another notable bearer of the name was Ieuan Brydydd Hir (Ieuan the Tall Poet), a 14th-century Welsh poet renowned for his intricate and lyrical compositions.
The name Ieuan also appeared in some Welsh literary works, such as the medieval prose tales known as the Mabinogion. One of the characters in the tale of Culhwch and Olwen was named Ieuan Lawnbedydd, or Ieuan the Tall.

Another notable figure was Ieuan Deulwyn (c. 1460-1532), a Welsh Renaissance humanist scholar and grammarian known for his work on the Welsh language.
