Ludwig of Bavaria
On 10 July 1900 in Munich at the Allerheiligen-Hofkirche, Marie Gabrielle married her second cousin once-removed, Prince Rupprecht of Bavaria. He was the eldest son of Prince Ludwig of Bavaria (later Prince Regent and King of Bavaria) and Maria Theresia of Austria-Este. The wedding was attended by Prince Joachim of Prussia, representing his father Emperor Wilhelm II. After their marriage, the couple settled down in Bamberg, Bavaria, where Rupprecht was head of an army corps. Their two eldest children were born there.
