[1] Her father was Hywel Fychan of Mechain in Powys,[2] her mother was named Gwenhwyfar, and she had at least four siblings (three brothers and a sister).
She married John ap Llywelyn Fychan and had at least one child, a daughter named Mawd.
Her work, composed in the traditional strict metres, including cywyddau and englynion, is often a celebration of religion or sex, sometimes within the same poem.
In it, she upbraids male poets for celebrating so many parts of a woman's body but ignoring "the girl's middle".
Many of her surviving poems are examples of ymrysonau (poetic or bardic rivalry)[1] with contemporaries such as Dafydd Llwyd of Mathafarn, Ieuan Dyfi and Llywelyn ap Gutun.
