The dates and chronology for having Hildegonde being married to both Willem van Brederode and Costijn van Renesse don't match up. I'm proposing another route - suggesting two Hildegonde from the same father, but different mothers. Please comment!
So I propose that the one with picture is the wife of Willem van Brederode and has a known death date and the other one is less famous and has no picture and death date. And married with Costijn van Renesse
This question was long enough open for discussion (8 years) so it is time to make choice.
