Thomas de Dent

Thomas de Dent, Thomas Dyvelyn, Thomas Denton, or Thomas of Dublin (died after 1361) was an English-born cleric and judge who held high office in Ireland during the reign of King Edward III, and was praised as a diligent and hard-working Crown official, who damaged his health through overwork.

He was born at Dent, then in the West Riding of Yorkshire (now in Cumbria), and may have been the son of John de Dent. During his years in Ireland he was sometimes known as Thomas Dyvelyn, which was an early form of "Thomas of Dublin", or as Thomas Denton. His petition to the Crown in 1358, confusingly, calls him both Thomas Dent and Thomas Dyvelyn.

He took holy orders, and became a clerk in the Royal service. He is first heard of in 1331 as the defendant in a lawsuit for poaching and trespass at Ingleton, North Yorkshire brought by John, 3rd Lord Mowbray; John de Dent, who was possibly his father, was named as co-defendant.
