Ieuan ab Owain Glyndŵr

Ieuan ab Owain Glyndŵr was reputedly the illegitimate son of the last native Welsh Prince of Wales; Owain Glyndŵr. The possibility of his existence was uncovered through the work of Peter Bartrum which is currently being edited by the University of Wales Aberystwyth. Ieuan ab Owain and his descendants are detailed in "Peniarth Manuscript 287" in the hand of [http://yba.llgc.org.uk/en/s-VAUG-ROB-1592.html Robert Vaughan of Hengwrt] (c.1592-1667) and also in the manuscript known as "Harley 1969" by Griffith Hughes (1634-1665) - the original manuscripts are kept at the National Library of Wales, Aberystwyth and the British Library respectively.

Ieuan, who is thought to have been born around 1380 and to have died around 1430, is thought to have had three sons:

* Maredudd ab Ieuan ab Owain Glyndŵr
* Robert ab Ieuan ab Owain Glyndŵr
* Iorwerth ab Ieuan ab Owain Glyndŵr
