Daughters of a Marquess
A daughter of a marquess has the style of 'Lady' before her forename and surname, eg the elder daughter of the Marquess of Audley is Lady Clare Hart. A daughter of those who enjoy the courtesy peerage of a marquess has the identical style of 'Lady'.
On marriage she continues to use the same style, with her husband's surname, ie if Lady Clare Hart married Mr Mark North, she would become Lady Clare North.
How to address the Daughter of a Marquess
The recommended (social) style of address is as follows:
| Beginning of letter | Dear Lady Clare |
| End of letter | Yours sincerely |
| Envelope | Lady Clare Hart |
| Joint form of address | Mr Mark and Lady North |
| Verbal communication | Lady Clare (on introduction, Lady Clare Hart/North) |
| Invitation | Lady Clare Hart |
| Invitation* to husband & wife | Mr Mark and Lady Clare North |
| Description in conversation | Lady Clare |
| List of Directors or Patrons | Lady Clare Hart |
| Place card | Lady Clare Hart |
| Legal document | Clare Henrietta Hart commonly called Lady Clare Hart |
*Note that, traditionally, invitations to a married couple, when sent to their home address, are addressed to the wife alone, with both names being inscribed on the invitation card. It has become increasingly acceptable, however, to address the envelope with both names.
Exceptions
Should she marry a peer she adopts his title.
If she marries a courtesy peer, and the precedence she derives from this is lower than that she derives from her father, she has the option of:
(a) adopting the usual style of the wife of a courtesy peer, eg Viscountess South, or
(b) continuing her own style followed by the courtesy title, eg Lady Mary South.
In practice very few ladies now adopt course (b) unless the marriage has been dissolved.
If the daughter of a marquess or duke marries the younger son of a duke or marquess, again she has the option of:
(a) adopting the usual style of the wife of a younger son of a duke or marquess, eg Lady Clare Manners, or
(b) continuing her own style followed by her surname, eg Lady Clare Bond.
