Overview
Gertrude of Dagsburg (died 30 March 1225) was the reigning countess of Metz and Dagsburg (Dabo) between 1212 and 1225. She was duchess consort of Lorraine by marriage to Theobald. She was a trouvère.
She was the daughter and heiress of Albert II, count of Metz and Dagsburg (Dabo).
Life
Gertrude was named after her mother, Gertrude of Baden, the daughter of Herman III, Margrave of Baden. The birth date of May 1205 (or as late as mid-1206) often assigned to her is questionable, as her mother was then 52 years old. A more plausible date is c. 1190.
