In connection with the Guelph inheritance division[1] after the Lords of Homburg died out, she transferred the castle and town of Gandersheim and the castles of Seesen and Stauffenburg to Otto II of Brunswick-Göttingen. She transferred Asseburg Castle, Gifhorn, Castle and City of Lüneburg, Greene Castle, Lüthorst, one half of the fief of Homburg, Lauenstein Castle, and the former County of Wernigerode to William I of Brunswick-Wolfenbüttel.[2]
