Ingeborg of Mecklenburg
Ingeborg of Mecklenburg (1343/45 – 25 July 1395) was a daughter of Albert II, Duke of Mecklenburg and his wife, Euphemia of Sweden. Euphemia was a daughter of Ingeborg of Norway, who was the only legitimate child of King Haakon V of Norway. Thus, Ingeborg of Mecklenburg was Haakon V's great-granddaughter. In 1360, she married Louis VI "the Roman" of Bavaria; she was his second wife. The marriage remained childless. After Louis's death, she married Henry II, Count of Holstein-Rendsburg. They had at least four children:
 Gerhard VI, Count of Holstein; married, in 1391, Catherine Elisabeth of Brunswick-Lüneburg and had issue. Albert II, Count of Holstein-Rendsburg
 Henry III, Count of Schauenburg-Holstein (d. 1421), Prince-Bishop of Osnabrück as Henry I
 Sofia of Holstein (1375, Lübeck – 1448); married, in 1398, Bogislaw VIII, Duke of Pomerania (1364–1418) and had issue. References
