There is evidence to suggest that both Máel Coluim and his father were amongst the assembled kings said to have convened with Edgar at Chester in 973. According to the "D", "E", and "F" versions of the "Anglo-Saxon Chronicle", after having been consecrated king that year, this English monarch assembled a massive naval force and met with six kings at Chester. By the tenth century, the number of kings who met with him was alleged to have been eight, as evidenced by the tenth-century "Life of St Swithun". By the twelfth century, the eight kings began to be named and were alleged to have rowed Edgar down the River Dee, as evidenced by sources such as the twelfth-century texts "Chronicon ex chronicis", "Gesta regum Anglorum", and "De primo Saxonum adventu", as well as the thirteenth-century "Chronica majora", and both the Wendover and Paris versions of "Flores historiarum".
