The couple were engaged on December 5, 1865, and married July 56, 1866. The Prince of Wales, who had threatened not to attend because of his wife's Danish connections, was present to accompany Helena and Queen Victoria up the aisle. The ceremony took place in the private chapel at Windsor Castle.
Like her sister Beatrice and her husband, Helena and her husband remained close to Queen Victoria and Helena, like Beatrice, served as a secretary to her mother.
Helena served as President of the British Nurses Association, in support of nursing. She and her husband celebrated their 50th wedding anniversary shortly before Christian's death.
