By some Dafydd was considered the most prominent Glamorganshire bard of the 17th century. According to
Iolo Morganwg, he was tutored by Llywelyn Siôn, who dwelt in
Laleston, a neighbouring parish. None of his work is thought to have been produced after 1665. Dafydd is believed to have been admitted as a graduate of the gathering known as Gorsedd Morganwg in 1620. In 1660, he served as its President. He died in 1690. ==References==
