"Adelbertus…comes Metensis et de Dasbourch" appointed "nepotem meum ducem Lotharingiæ" as his heir "de castro meo Dasbourgh et abbatia de Hessen, de castro Gerbaden, abbatia de Altorf, de castro de Drotein, de castro Albapai, de abbatia et advocatia de Herbreheym…comitatu et advocatia…de Metis…allodium de Musal et Waleve"[298].

Gertrude of Baden (before 1160 – before 1225) was a Margravine of Baden by birth and by marriage a Countess of Dagsburg. She was a daughter of Margrave Hermann III of Baden and his wife, Bertha of Tübingen.

Marriages and issue

Gertrude married in 1180 to Albert II of Dagsburg (d. 1211). With him she had two sons, Henry and William, and a daughter, Gertrude (d. 1225). Both sons were killed in a tournament in Andain in 1202, so that the noble family of the Etichonids died out in the male line with Albert II in 1211. This left her daughter Gertrude as heiress of the county of Dagsburg.

Her daughter Gertrude married in 1215 in her first marriage to Duke Theobald I of Lorraine. In 1217, she married her second husband, Count Theobald IV of Champagne, who was also King of Navarre from 1234 as Theobald I. Theobald, however, repudiated her before 1223. In 1224, she married her third husband, Simon III of Saarbrücken and Leiningen (d. 1234/36), the son of Count Frederick II of Leiningen and Saarbrücken. When she died childless, her third husband Simon of Leiningen inherited the county of Dagsburg, thus creating the Leiningen-Dagsburg line.
