Maredudd ap Tudur

Maredudd ap Tudur (died c. 1406) was a Welsh soldier and nobleman of the Penmynydd family on Anglesey, the youngest of the six sons of Tudur ap Goronwy.

With his brothers Rhys and Gwilym he supported their cousin Owain Glyndŵr's revolt against Henry IV from 1400, though less prominently; the family lost most of its lands as a result. His son Owain anglicised his name to Owen Tudor and became grandfather of Henry VII.
