sentences:  The "Anglo-Saxon Chronicle" for 763 states that Pehthelm's successor, Frithwald, had died that year, and provides a rough dating for the start of his episcopacy at Whithorn.This allows the date of Pehthelm's death to be estimated at 735 or 736.In a very old (811 – 814) manuscript of Northumbrian genealogies, Pehthelm appears first in the list of bishops at Candida Casa.
