Career
A native of Cambridgeshire, de Fulbourn was translated to Tuam by a Papal bull dated 12 July 1286, having previously been Bishop of Waterford. He served as Treasurer of Ireland from 1274-1277 and Justiciar of Ireland from 1281-1288. The History of the Popes states that his appointment took place:
According to Otway-Ruthven, his tenure as Justiciar was plagued by accusations of corruption and inefficiency.
He gave his name to the steeping, a debased form of the sterling silver penny.
This was outlawed by Edward I.
De Fulbourn received possession of the temporalities 15 September 1286. He died in Dublin on 3 July 1288 and was buried in Christ Church Cathedral, Dublin.
