The counts of Moosburg hold the lower Isar round their castle at Moosburg, where they are the hereditary advocates of the collegiate church of St Kastulus.
Their county was rounded off by 1179 at the latest, and Konrad II shared the inheritance of the extinct counts of Roning (house monastery Paring) with the Wittelsbach. The county also takes in stretches of the Isar banks and the lordship of Au in the Hallertau. The line lasts until 1281.
