Bishops' Wives and Children have no titles.
Clergy—'The Rev.' [Christian name and surname]. Begin: 'Rev. Sir.' If son of a Duke or Marquess, 'The Rev. Lord' [Christian name and surname]. If the son of an Earl, Viscount, or Baron, 'The Rev. the Hon.' [Christian name and surname] is beginning to supersede 'The Hon. and Rev.' The Moderator of the General Assembly of the Church of Scotland during his year of office is styled 'Right Rev.;' ex-moderators are usually spoken of as 'Very Rev.'
Companion of an Order of Knighthood—The initials, C.B., C.M.G., C.S.I., or C.I.E., as it may be, are subjoined to the ordinary form of address.
Consul, British—'—— ——, Esq., H.B.M.'s Agent and Consul-General,' 'Consul-General,' 'Consul,' or 'Vice-Consul,' as it may be.
Countess—'The Right Hon. the Countess of ——.' Begin: 'Madam.' Refer to as 'Your Ladyship.'
Dean—'The Very Rev. the Dean of ——.' Begin: 'Very Rev. Sir.'
Doctor—The initials D.D., M.D., LL.D., Mus.D., are placed after the ordinary form of address, as 'The Rev. John Davidson, D.D.,' 'David Patrick, Esq., LL.D.' But 'The Rev. Dr Davidson,' 'Dr David Patrick,' are also frequently used.
Dowager—On the marriage of a peer or Baronet, the widow of the previous holder of the title becomes 'Dowager,' and is addressed, 'The Right Hon. the Dowager Countess of ——,' 'The Dowager Lady ——.' As more than one Dowager may hold the same title, the term is less used than formerly, and the Christian name is instead coming to be employed as a distinction—e.g. 'The Right Hon. Helen Countess of ——.'
Duchess—'Her Grace the Duchess of ——.' Begin: 'Madam.' Refer to as 'Your Grace.'
Duke—'His Grace the Duke of ——.' Begin: 'My Lord Duke.' Refer to as 'Your Grace.'
