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 Lothian is Lady Clare Kerr. 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 when Lady Henrietta Dundas married Mr Mark Stroyan, she became Lady Henrietta Stroyan.
How to address the Daughter of a Marquess
The recommended (social) style of address is as follows:
| Beginning of letter | Dear Lady Henrietta |
| End of letter | Yours sincerely |
| Envelope | Lady Henrietta Stroyan |
| Joint form of address | Mr Mark and Lady Stroyan |
| Verbal communication | Lady Henrietta (on introduction, Lady Henrietta Stroyan) |
| Invitation | Lady Henrietta Stroyan |
| Invitation* to husband & wife | Mr Mark and Lady Henrietta Stroyan |
| Description in conversation | Lady Henrietta |
| List of Directors or Patrons | Lady Henrietta Stroyan |
| Place card | Lady Henrietta Stroyan |
| Legal document | Henrietta Kate Stroyan commonly called Lady Henrietta Stroyan |
*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 Countess of Twickenham, or
(b) continuing her own style followed by the courtesy title, eg Lady Mary Twickenham.
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 Charles Manners, or
(b) continuing her own style followed by her surname, eg Lady Mary Manners.
