Notes for Robert II de Namur: This does not agree with the "Ancestral Roots" book but does not change the blood line to Charlemagne. Robert II is missing from the lineage in Ancestral Roots but included in the book The Ancestry of Thomas Bradbury....See note on Albert I.
From the book "The Ancestry of Thomas Bradbury and his Wife Mary Perkins" page 440:
"Historians of Namur contend that Robert II was the son of Albert I and Ermengarde, and was Albert II's older brother, although the proof is lacking. Unless they were by two wives and many years apart in age, the chronology looks doubtful and it seems more likely that Albert II was the son of Robert II, rather than a younger brother. As for the wives, that presents a confusing problem unless both wives were named Ermengarde. But which one was the Carolingian princess, daughter of Charles of France? The chronology would suggest clearly that Ermengarde, alledged to have been the daughter of Charles of France, must have been the wife of Robert II. If Ermengarde, wife of Albert I, was the princess as stated in the gemealogy of Godfrey of Bouillon, then she had to have been the second wife and a generation younger than her husband. There are clear contradictions in the several accounts outlined so far. It seems more logical to assume normal generation spans and ages."
