Adelheid of Wolfratshausen (d. 11 January/12 January 1126) was the second wife of Berengar II, Count of Sulzbach. Slightly different dates for her death are given in the necrologies of Tegernsee and the Salzburg Cathedral.[1]


Adelheid was a daughter of Otto II, Count of Wolfratshausen and his wife Justizia. Otto was created Count between 1098 and 1116. He was also Count of Thaining (c. 1073), Count of Ambras (c. 1078) and Count of Diessen (c. 1100). The family name of her mother is not attested in primary sources. Theories suggest Justizia was a member of the House of Babenberg. They are based on the transmission of the first name "Luitpold", previously used by the Babenberg, which was used by several of Justizia's descendants.[2]

Her paternal grandparents were Berthold I, Count of Diessen and his unnamed wife. The work "Genealogischen Tafeln zur mitteleuropäischen Geschichte" (1965–1967) by Wilhelm Wegener introduced a theory that Berthold I was married to a member of the Hohenwart family, a line of the wider Ratpotonen dynasty. The theory was based on the transmission of the first name "Konrad" from the Ratpotonen to the Counts of Diessen and their descendants. The theory would also explain why the Counts of Diessen held property previously owned by the Ratpotonen.[3] Theories differ on the identity of her maternal grandparents. Wegener suggested they were Liutpold, Margrave of the Hungarian March and his unnamed wife.[2] This Liutpold was a son of Adalbert, Margrave of Austria. He reigned briefly in the Hungarian March and died on 9 December 1043. There are theories identifying him with the namesake first husband of Ida of Elsdorf. Ida being a daughter of Liudolf, Margrave of Frisia. However primary sources do not mention a widow or children of Liutpold.[4] The "Europäische Stammtafeln: Stammtafeln zur Geschichte der Europäischen Staaten" (1978) by Detlev Schwennicke, suggested her maternal grandparents were Ernest, Margrave of Austria, a younger brother of Liutpold, and his first wife Adelheid of Wettin.[5]

Adelheid of Wettin was a daughter of Dedi I, Margrave of the Saxon Ostmark and his first wife Oda of Ostmark. He inherited Ostmark by right of this marriage.[6] Her maternal grandfather were Thietmar, Margrave of the Saxon Ostmark. The identity of her maternal grandmother is unknown.[6]


Adelheid married Berengar II, Count of Sulzbach. They had six known children:[7]
