Aldadus, Eldaldus
The Bishop of Gloucester and the brother of Eldol, Earl of Gloucester.
A moral and pious man, Eldad buried the British warriors who died at the battle of Ambrius’s Monastery. He advocated the execution of Hengist (which was carried out by Eldol), and the granting of mercy to Octa and Eosa. He advised Ambrosius Aurelius to give the barren Scotland to the Saxons as a peace offering.
