I have a doubt about royal titles:
Sarah Ferguson lost the title of Duchess of York if Andrew marries again?
Does she really holds this title?
Sarah does not hold the title of The Duchess of York. As former wife of a peer, she is styled and titled Sarah, Duchess of York; she will hold both for life, unless she remarries. If Andrew were to remarry, that would not affect Sarah's style at all. Andrew's new wife would be titled The Duchess of York, whereas his former wife would be Sarah, Duchess of York.
To explain better:
- While Sarah was married to Andrew, she was HRH The Princess Andrew, Duchess of York. In the same way, the current wife of Mr. John Brown is Mrs. John Brown.
- After the divorce, Sarah has been titled as Sarah, Duchess of York. In the same way, the former wife of Mr. Brown would be titles "Name", Mrs. Brown (as opposed to Mrs. John Brown).
Take the example of the Earl Spencer:
- His current wife, Karen Gordon, is The Right Honourable The Countess Spencer.
- His first wife, Victoria Lockwood, was The Right Honourable The Countess Spencer. After their divorce and until remarrying she was Victoria, Countess Spencer.
- His second wife was Mrs. Caroline Freud. She was born Caroline Hutton and was married to Matthew Freud in her first marriage; for the duration of that union, she was Mrs. Matthew Freud. Following the divorce, she came to be known as Mrs. Caroline Freud. After her marriage to Earl Spencer, she was The Right Honourable The Countess Spencer until the divorce. After her second divorce, she was titled Caroline, Countess Spencer.
