Following that year's Treaty of Union, the Kingdom of Scots and the Kingdom of England were combined under the name of Great Britain, and a new Peerage of Great Britain was introduced in which subsequent titles were created.
Unlike most peerages, many Scottish titles have been granted with remainder to pass via female offspring (thus an Italian family has succeeded to and presently holds the earldom of Newburgh[1]), and in the case of daughters only, these titles devolve to the eldest daughter rather than falling into abeyance (as is the case with ancient English baronies by writ of summons).
[2][3] The ranks of the Scottish Peerage are, in ascending order: Lord of Parliament, Viscount, Earl, Marquess and Duke.
The Peerage of Scotland differs from those of England and Ireland in that its lowest rank is not that of baron.
[4] This reform "expressly preserves the dignity of baron... and any other dignity or office, whether or not of feudal origin," converting feudal titles into non-territorial dignities—personal titles no longer attached to the land, including the quality, precedence, and heraldic rights pertaining.
