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.
Adalrich, Duke of Alsace Adalrich (Latin: "Adalricus" ; reconstructed Frankish: "*Adalrik"; died after 683 AD), also known as Eticho, was the Duke of Alsace, the founder of the family of the Etichonids and of the Habsburg, and an important and influential figure in the power politic of late seventh-century Austrasia.
