Carloman of Bavaria was the eldest grandson of what descendant of Charlemagne?
Carloman of Bavaria Carloman (German: "Karlmann" , Latin: "Karlomannus" ; c. 830 – 22 March 880), was a Frankish king of the Carolingian dynasty. He was the eldest son of Louis the German, king of East Francia, and Hemma, daughter of a Bavarian count. His father appointed him margrave of Pannonia in 856, and upon his father's death in 876 he became King of Bavaria. He was appointed by King Louis II of Italy as his successor, but the Kingdom of Italy was taken by his uncle Charles the Bald in 875. Carloman only conquered it in 877. In 879 he was incapacitated, perhaps by a stroke, and abdicated Bavaria to Louis the Younger and Italy to Charles the Fat.
Ferdinand of Bavaria (bishop) Ferdinand of Bavaria (German: "Ferdinand von Bayern" ) (6 October 1577 – 13 September 1650) was Prince-elector archbishop of the Archbishopric of Cologne (Holy Roman Empire) from 1612 to 1650, as successor of Ernest of Bavaria. He was also prince-bishop of Hildesheim, Liège, Münster, and Paderborn.
