Both of these junior titles were in the Peerage of Ireland, although they referred to places in Scotland – namely Braco and Macduff in Banffshire.

Between 1790 and 1885, the Earls Fife received several additional titles in the Peerage of Great Britain and of the United Kingdom, respectively, which allowed them to sit and vote in the House of Lords.

In 1889, the 6th Earl Fife was further created Duke of Fife, in Scotland, and Marquess of Macduff, in the County of Banff, in the Peerage of the United Kingdom, two days after his marriage to Princess Louise of Wales, the eldest daughter of Albert Edward, Prince of Wales (the future King Edward VII).

When it became clear that he would have no sons, he was further created Duke of Fife and Earl of Macduff, in the County of Banff, also in the Peerage of the United Kingdom, with a special remainder to his daughters and their heirs male.

The second Dukedom of Fife and the Earldom of Macduff passed by their special remainders to his daughters and their heirs male.
