It's quite true that the Melusine myth was very important to the Burgundians. Just as many of the nobility tried to trace their lineage back to gods, the Burgundians did so with the Melusine as well.

Also, when you leaf through manuscripts from the Burgundian libraries, the chain representing the order of the golden fleece is everywhere. It is prominently displayed around the necks in chronicles and in illuminations of the patrons.

I think R. Sale has a good case for a possible connection.
