Okay, so I was playing around with a scenario with Olaf II marrying Isabelle of Bourbon, and I was looking for a bride for a potential son of theirs, probably born between 1400-1410. I wanted to look for potential imperial, I.e Luxembourg matches but they are notoriously short on princesses in this era - except for Elizabeth of Luxembourg of course, but I doubt Sigismund would give her to a foreign king.
That lead me down looking for potential Luxembourg-related ones, and it led me to
her: She’s Sigismund of Luxembourg’s first cousin twice removed, so not a very close connection, but seemingly the closes female Luxembourg-related woman I could find. How’d she be for a son of Olaf and Isabelle?
I mean, it’s a bit random, but not more so than Blanche of Namour a few generations back. And early 15th century is pretty short on princesses in general I find.
