... The monks of Crowland were, perhaps, trying to work on Hugh Evermue, Hereward's son-in-law, or Richard of Rulos, his grandson-in-law, as they were trying to work on the Norman kings, when they invented these charters of the eighth and ninth centuries, with names of Saxon kings, and nobles of Leofric and Godiva's house; or, again, the land being notoriously given to Crowland by men of certain names, who were then of no authority as rebels and dispossessed, it was necessary to invent men of like names, who were safely entrenched behind Saxon antiquity with the ancestors of Edward the Confessor.  But in their clumsiness they seem to have mingled with them in the said charters and their mythic battles against the Danes, purely Danish names, such as siward, Asketyl, Azer, Harding, Grimketyl, Wulfketyl, etc., which surely prove the fraud...
