Boulers became abbot of the abbey of St Peter at Gloucester in 1437.
[1] Boulers was a shrewd man of affairs and was sent on an embassy to Rome in 1449, when the convent allowed him £400 for his expenses.
[1] In 1450, he was seized by Richard Plantagenet, 3rd Duke of York, and imprisoned for a time in Ludlow Castle.
[1] In the same year, Boulers was appointed to the See of Hereford on 14 August 1450 and consecrated on 14 February 1451.
[5][6][7] Shortly before his death he willed his books to the library at Gloucester Abbey.
