John Howard, the First Duke of Norfolk, was killed at the Battle of Bosworth in 1485 where he was commanding the part of Richard III’s army.
His tomb appears to be located in a tomb constructed on the north side of the aisle of the church at Thetford Priory, and adjacent to the north transept. The body may have been moved to St Michael’s, Framlingham.
The tomb of Thomas Howard (1443-1524), Second Duke of Norfolk, was placed at the east end of the original church (that had been extended). He defeated the army of James IV of Scotland at Flodden in September 1513.
Howard died at Framlingham Castle in May 1524 and his body was buried at Thetford.
