In his youth he was involved in an attack on Llanthony prior Nicholas de Trinbey. Nicholas was blinded, and his brother killed. In later life his enemies accused him of being a follower of Welsh rebel Owain Glyndŵr.

On or around 4 August 1373 Nicholas de Trinbey and his brother John were attacked by de Welyngton and two other canons of Llanthony while Nicholas was saying the Office of the Dead. John de Trinbey was killed and Nicholas was thrown to the ground and his eyes torn out. In 1399 he nominated Elmeley and William Hamelyn for three years. In 1400, he again nominated Elmeley and Philip White of Hulleton for two years.

With the permission of the king he travelled to Ireland in 1402. In his absence he nominated Hugh Harper, his chaplain, and William Harper to serve as his authorised representatives in England for one year.

On 24 October 1402 he was granted permission by Guy Mone, bishop of St Davids, to have ordained three canons of Llanthony, including William Cromp. On the same day Mone charged him and two others with investigating accusations of perjury against two brothers.
