The Deeds of Wiprecht

The way these names have been appended to the sentence describing Kunigunde's situation after her first husband's death suggests they may not have been included when this section was originally composed, but instead represent a marginal notation later integrated into the body of the Deeds.

Elger of Ilfeld and Christian of Rothenburg are otherwise unknown.  Their designations here indicate they were nobles.  

The murder of the important Saxon magnate, Kuno of Beichlingen, is reported in other sources but none names specific individuals as responsible.
