Daughters of a Baron

A daughter of a baron bears the courtesy style of 'The Honourable' (usually abbreviated to 'The Hon').

When she is unmarried this style is followed by her forename (eg The Hon Jane White). After marriage she drops the use of her forename and uses her surname only (eg The Hon Mrs Smith). The style of 'The Hon' is not used before 'Miss'.

The style of 'The Hon' is only used on the envelope in correspondence, in written descriptions (usually only on the first mention) and in formal documents. It is never used in conversation or on invitations or on visiting cards, when the correct style is 'Mrs', 'Miss' or 'Ms'.
