Sarah Ferguson
The Duchess of York is Sarah Ferguson, ex-wife of Prince Andrew, the son of Queen Elizabeth II. ---- Before her divorce from the duke of York, Sarah Ferguson enjoyed the style and title of Her Royal Highness the Duchess of York. Since the divorce, she no longer bears that style and title. Instead, as is customary among the divorcees of men with titles, the former duchess affixed her former title to her Christian name, and uses it as if it were a surname. She goes by the name "Sarah Duchess of York" Presently there is no one with the actual title The Duchess of York, which Sarah used to use, and there won't be unless and until the duke of York remarries, at which time his new wife will enjoy that title.

SPENCER
The queen has 8 grandchildren. Her 6th grandchild is called Princess Eugenie Victoria Helena of York. She was born on the 23rd of March 1990 and is the daughter of Prince Andrew, Duke of York and Sarah, Duchess of York.
Since her divorce (and after she lost the style Her Royal Highness due to new letters patent being issued) her name is simply "Sarah, Duchess of York" She is neither a princess, nor a duchess, rather simply a wife a a divorced British duke. I suppose Mrs. Duchess of York would therefore be appropriate, as she has no other title. Your Royal Highness would be incorrect, as she does not have this style any longer. Your Grace (the style for the wife of a duke) is not longer appropriate, as she is no longer the wife of a duke. And, she was never a princess in her own right, but by marriage. I suppose one could call her Duchess out of courtesy, but it is kind of like calling someone by their last name. She is not The Duchess of York any longer.
The Prince Andrew, Duke of York Married Sarah Margaret Ferguson on 23 July 1986 she became Her Royal Highness The Duchess of York, they got divorced on 30 May 1996 and she became Sarah, Duchess of York loosing the right to use "Her Royal Highness" before her name
