Hawys Gadarn (Hawys ferch Owain ap Gruffudd ap Gwenwynwyn), also known as the Hardy, the Powerful, the Intrepid, and Hawise de la Pole, (1291 – c. 1353) was the daughter of Owen de la Pole and the heir to Powys Wenwynwyn in Wales.
She was married to John Charleton after seeking the intervention of Edward II of England to support her inheritance against the schemes of four of her uncles to take her lands.
[2] Owen was the heir to the Powys Wenwynwyn, but had renounced his claim and was given the Barony under the crown of King Edward I of England.
[3] Because she was a woman, four of her uncles disputed her claim on the grounds that she could not inherit property,[4] and sought to split the land between themselves.
[4] Together with Charleton and a company of English knights, she returned to Powis Castle anticipating that her uncles may choose to fight to defend their rights under Welsh law.
