谁嫁给了Louis II, Elector of Brandenburg？

Louis the Roman (German: Ludwig VI der Römer) (7 May 1328 – 17 May 1365) was the eldest son of Holy Roman Emperor Louis IV by his second wife, Margaret II, Countess of Hainaut, and a member of the House of Wittelsbach. Louis was Duke of Upper Bavaria as Louis VI (1347–1365) and Margrave of Brandenburg (1351–1365) as Louis II. As of 1356, he also served as Prince-Elector of Brandenburg.

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.
