[8] A celebratory ball was held later that evening, where she was introduced to Georg Ritter von Trapp, a nobleman and naval officer who would eventually be assigned to command SM U-5.

[2] After a two-year courtship, Whitehead and von Trapp were married on 14 January 1911 in a Catholic ceremony at the Austro-Hungarian Naval Academy's chapel.

[2][8] After their wedding, the couple moved into the von Trapp family's villa in Pola, near the Austro-Hungarian Navy's submarine base.

[2][11][12] After the assassination of Archduke Franz Ferdinand in 1914 and the start of the First World War, Whitehead's family's assets overseas were frozen and they were not permitted to leave the country.

[2] When the war ended, and the Austro-Hungarian Empire fell, the family were granted Italian citizenship since Zara, where Georg von Trapp was born, was annexed to the Kingdom of Italy.
