Cathedral chapter
Haziga of Diessen, also known as "Hadegunde" ( – 1 August 1104) was a Countess consort of Scheyern. Her descent is not entirely clear. It is usually assumed that her father was Count Frederick II of Diessen. He was Vogt of the Cathedral chapter in Regensburg. He was married three times; it is unclear in which marriage Haziga was born.
