On 7 May, in Kassel, and then, again, on 1 June 1818 at Buckingham Palace, Princess Augusta married her second cousin, the Duke of Cambridge, when she was 20 and he 44. Upon their marriage, Augusta became Duchess of Cambridge. They had three children.
From 1818 until the accession of Queen Victoria, and the separation of the British and Hanoverian crowns in 1837, the Duchess of Cambridge lived in Hanover, where the Duke served as viceroy on behalf of his brothers, George IV and William IV. Hanover had been liberated from French occupation in 1813 and the dynastic union with Britain restored.
In 1827 Augusta allowed that a new village, founded on 3 May 1827 and to be settled in the course of the cultivation and colonisation of the moorlands in the south of Bremervörde, would bear her name. On 19 June the administration of the Hanoveran High-Bailiwick of Stade informed the villagers that she had approved the chosen name Augustendorf for their municipality (since 1974 it is a component locality of Gnarrenburg). The Duke and Duchess of Cambridge returned to Great Britain, where they lived at Cambridge Cottage, Kew, and later at St. James's Palace.
Death
The Duchess of Cambridge survived her husband by thirty-nine years, dying on 6 April 1889, at the age of ninety-one, at their home at Cambridge Cottage on Kew Green.[1] Queen Victoria wrote of her aunt's death: "Very sad, though not for her. But she is the last of her generation, & I have no longer anyone above me."
The generations include wives of princes descended from George I, who formalised the use of the titles prince and princess for members of the British royal family.
