I am descended from Edward Atheling,died 1057AD, the father of St Margaret. Edward Atheling's wife is reported as Agatha of Germany. I am trying to find her correct parentage. George A. Moriarity in Plantagenet Ancestry on page 21 lists her father as Bruno of Germany. C. M. Allstrom in Dictionary of Royal Lineage lists her father as Henry II of Germany( Saint Henry ). Frederick Weis in Ancestral Roots suggests that an article in volume 7 of the Duquesne Review may have Agatha's correct ancestry. I don't have access to that source. Does anyone have her most probable ancestry?
