Daughters of a Duke
A daughter of a duke has the style of 'Lady' before her forename and surname, eg Lady Rachel Bond.
On marriage she continues to use the same style, with her husband's surname, eg ie when Lady Rachel Bond married Mr Guy Green, she became Lady Rachel Green.
Should she marry a peer she adopts his title.
How to address the Daughters of a Duke
The recommended (social) style of address is as follows:
| Beginning of letter | Dear Lady Rachel |
| End of letter | Yours sincerely |
| Envelope | Lady Rachel Bond |
| Joint form of address | Mr Guy and Lady Rachel Green |
| Verbal communication | Lady Rachel (on introduction, Lady Rachel Bond/Green) |
| Invitation | Lady Rose Bond |
| Invitation* to husband & wife | Mr Guy and Lady Rose Green |
| Description in conversation | Lady Rachel Bond |
| List of Directors or Patrons | Lady Rachel Bond |
| Place card | Lady Rachel Bond |
| Legal document | Olivia Rachel Mildred Bond commonly called Lady Rose Bond |
*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
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 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 Bond, or
(b) continuing her own style followed by her surname, eg Lady Mary Bond
