She later met with Prince Leopold, Duke of Albany, youngest son of Queen Victoria, at the suggestion of his mother. The two became engaged in November 1881.
On 27 April 1882, Leopold and Helen married in St. George's Chapel, Windsor Castle.[3] After their wedding, Leopold and Helen resided at Claremont House. The couple had a brief, but happy marriage, ending in the hemophiliac Leopold's death from a fall in Cannes, France, in March 1884. At the time of Leopold's death, Helen was pregnant with their second child.
The couple had two children:
Princess Alice of Albany (1883–1981), later Countess of Athlone
Prince Charles Edward, Duke of Albany (1884–1954), later Duke of Saxe-Coburg and Gotha.
