 He pointed out that the Anglo-Saxon Chronicle represents the earliest surviving testimony, and argues that it was contemporary with Agatha and was very probably well informed in reporting an Imperial kinship.Parsons stresses that the sources claiming Russian parentage for Agatha, and her kinship with a Hungarian queen, are of much later date, and consequently likely to be less reliable than a source contemporary with her.Purely in an attempt to show that not all avenues have been fully pursued in the effort to identify Agatha, Parsons pointed to the documented existence of a German Count Cristinus, whose given name might explain the name Christina for Agatha's daughter.
