Chest of Books has this about the Duchess: "The marriage of the Duke of Manchester to Miss Helene Zimmerman, of Cincinnati, in 1900, was quite a romance. The marriage took place in the quietest possible fashion at Marylebone Church, and for a long time there were all sorts of rumours as to the displeasure of Mr. Zimmerman, the famous railway magnate. This displeasure, however (if it ever existed), has long passed away. Soon after the marriage, the Duchess took an important place in Anglo-american society. Queen Alexandra showed special favour to Her Grace, who was first presented to her Majesty on the occasion of the christening of the Duke of Manchester's son and heir, Viscount Mandeville. The Viscount has one brother and two sisters, and the Duchess likes nothing better than to spend her time with her children at Kyle-more Castle, Ireland. She is fond of country life, golf, cycling and motoring, although, perhaps, her favourite mode of conveyance is a donkey chaise, with her little son as charioteer."
