tends to be used when a landed family is not in possession of any United Kingdom peerage title of higher rank, subsequently granted, or has been created a knight of the realm. The name recorded by the Lord Lyon as part of any grant of arms or matriculation becomes the holder's name for all official purposes. The holder of a Scottish barony (e.g., "Inverglen") may add the title to their existing name (e.g., "John Smith, Baron of Inverglen" or "Jane Smith, Baroness of Inverglen") or add the territorial designation to their surname if still in possession of the caput ("John Smith of Inverglen, Baron of Inverglen" or "Jane Smith of Inverglen, Baroness of Inverglen"); some of the oldest Scottish families prefer to be styled by the territorial designation alone ("Smith of Inverglen"). Formal and in writing, they are styled as The Much Honoured Baron/Baroness of Inverglen. A baron/baroness may be addressed socially as "Inverglen" or "Baron/Baroness" and introduced in the third person as "John Smith of Inverglen, Baron of Inverglen" or "The Baron of Inverglen" or "Jane Smith, Baroness of Inverglen" or "The Baroness of Inverglen". When referred to informally in the third person it is incorrect to refer to them as "Baron/Baroness Inverglen" or "Lord/Lady Inverglen", as these would imply a peerage title (i.e. Lord of Parliament) In a heterosexual married couple, if the husband is the holder of the Barony, the wife receives a courtesy title. Therefore, they may be styled "The Baron and Baroness of Inverglen", "Inverglen and Madam Smith of Inverglen", "Inverglen and Lady of Inverglen", or "The Baron of Inverglen and Lady of Inverglen." The oldest son of a feudal baron/baroness may be known by the territorial designation with the addition of "yr" (abbreviation for "younger"), e.g. "John Smith of Inverglen, yr". The eldest daughter is may be known as "Maid of [Barony]" at the end of her name, e.g. "Sandra Smith, Maid of Inverglen". The husband of a Baroness is not afforded a courtesy title. The United Kingdom policy of using titles on passports requires that the applicant provides evidence that the Lord Lyon has recognised a feudal barony, or the title is included in Burke's Peerage. If accepted (and if the applicant wishes to include the title), the correct form is for the applicant to include the territorial designation as part of their surname (Surname of territorial designation e.g. Smith of Inverglen).
