Walter Trail
Walter Trail was a late 14th century Bishop of St. Andrews. He appears as an official in the Bishopric of Glasgow in 1378, as a Magister Artium and a Licentiate in Canon and civil law. In 1380, he has a Doctorate in Canon and Civil Law, as well as a Papal chaplain and auditor. In this year, Pope Clement VII granted him the deanery of the Bishopric of Dunkeld. He became treasurer of the Bishopric of Glasgow in either 1381 or 1382. On 29 November 1385, the Pope provided him to the vacant Bishopric of St. Andrews, vacant because of the capture and death of the previous bishop-elect, Stephen de Pa.
Walter Trail was an active bishop, and ardent defender of the rights of the church within Scotland. Walter constructed the castle at St. Andrews. It was there that he died in 1401.
