Former Wife of a Marquess
If a marriage between a marquess and marchioness has been dissolved, the former wife (although no longer a peeress) may continue to use her title as a marquess's wife, preceded by her forename (unless she remarries*).
How to address the Former Wife of a Marquess
The recommended (social) style of address is as follows:
|Beginning of letter||Dear Lady Ailesbury|
|End of letter||Yours sincerely|
|Envelope||Caroline, Marchioness of Ailesbury|
|Verbal communication||Lady Ailesbury|
|Invitation||Caroline, Lady Ailesbury|
|Description in conversation||Lady Ailesbury|
|List of Directors or Patrons||Caroline, Marchioness of Ailesbury|
|Place card||Caroline, Marchioness of Ailesbury|
|Legal document||Caroline, Marchioness of Ailesbury|
*If the former wife of a marquess subsequently remarries she adopts her style of address from her present husband. Thus if Caroline, Marchioness of Ailesbury, marries Mr Cuthbert Robinson she becomes Mrs Cuthbert Robinson.
