What cousin of Herman I, Duke of Swabia also had a chance to rule the Duchy of Franconia?
Conrad I of Germany Conrad I (German: "Konrad" ; c. 881 – December 23, 918), called the Younger, was the first non-Carolingian king of East Francia from 911 to 918. He was the first elected king of East Francia and also the first one to be anointed. He was chosen as the king by the rulers of the East Frankish stem duchies after the death of young king Louis the Child. Prior to this election he had ruled the Duchy of Franconia from 906.
Pribislav-Henry Pribislav-Henry (German: "Pribislaw-Heinrich" ; d. 1150) was a Slavic Christian prince and the last ruler of the Hevelli (Stodorani) tribe in the Northern March of Brandenburg. His reign started, probably supported by the Ascanians, after the prior Hevelli prince Meinfried had been murdered in 1127. Having no sons of his own, he around 1129 gave the area between Brandenburg and Lehnin to his son-in-law, who was the oldest son of Albert the Bear. Emperor Lothair III approved the gift and made Albert margrave of the Northern March in 1134. In 1150, Pribislav Henry died and was succeeded, after a short war of succession, by Albert the Bear.
