Carte-de-visite photograph of Princess Louise, later Duchess of Argyll, in her wedding dress, looking downwards. Vignette.

Princess Louise married John Campbell, Marquess of Lorne on 21 March 1871. He was the first 'non-royal' male to marry into the British royal family, and there was some opposition to the match but Queen Victoria was supportive and thought the marriage would help strengthen the Royal family. Indeed it was a happy marriage to begin with, but after some years of childlessness and Queen Victoria's constraints on their activities, the couple drifted apart. They did reconcile about 1911 before Lorne's death in 1914.
