Question: Who is the mother-in-law of Bertrude?
Sentence (from "Bertrude"): Because Chlothar had three wives (Haldetrude, Bertrude, and Sichilde) and it is not known which was mother of his sons Dagobert I and Charibert II, it is not clear this daughter of Richomer was Bertrude.
Relevant evidence: No
