Louis the German
In 827, probably at the instigation of Judith, Hemma married Louis the German, the youngest son of Emperor Louis the Pious from his first marriage with Ermengarde of Hesbaye, and stepson of Hemma's sister Judith. The wedding ceremony possibly took place in Regensburg, where Louis the German resided as King of Bavaria subordinate to his father. In 833, Hemma received Obermünster Abbey in Regensburg from her husband.
