This documented Lineage, I received from my mother's research. It is the true blood Lineage from France. Son of Berthold, the Fourth and Agnes von Rochlitz, husband of Beatrice of Burgundy, believed to have later, had wife, Sophie. More research needed than I have time to give. It all has been documented in the 1960-1980 date range by earlier family descendant researchers. This is the closest I have seen to the actual research papers, that I recall seeing.
