Slightly different dates for her death are given in the necrologies of Tegernsee and the Salzburg Cathedral.
[citation needed] Adelheid was a daughter of Otto II, Count of Wolfratshausen[1] and his wife Justizia.
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.
[citation needed] Adelheid married Berengar II, Count of Sulzbach.
