Duke of Westminster

Template:Short description Template:Use dmy dates Template:Infobox nobility title Template:Infobox nobility title

Duke of Westminster is a title in the Peerage of the United Kingdom. It was created by Queen Victoria in 1874 and bestowed upon Hugh Grosvenor, 3rd Marquess of Westminster. It is the most recent dukedom conferred on someone not related to the British royal family.^[1]

The 2nd, 3rd, 4th and 5th Dukes were each grandsons of the first. The present holder of the title is Hugh Grosvenor, the 7th Duke, who inherited the dukedom on 9 August 2016 on the death of his father, Gerald. The present duke is a godfather of Prince George of Wales.^[2]

The Duke of Westminster's seats are at Eaton Hall, Cheshire, and at Abbeystead House, Lancashire. The family's London town house was Grosvenor House, Park Lane, while Halkyn Castle was built as a sporting lodge for the family in the early 1800s. The traditional burial place of the Dukes is the Old Churchyard adjacent to St Mary's Church, Eccleston.

History of the Grosvenor family

Richard Grosvenor was created Baronet of Eaton in January 1622.^[3] Sir Richard Grosvenor, the 7th Baronet, was created Baron Grosvenor in 1761, and in 1784 became both Viscount Belgrave (Belgrave, Cheshire) and Earl Grosvenor under George III. The title Marquess of Westminster was bestowed upon Robert Grosvenor, the 2nd Earl Grosvenor, at the coronation of William IV in 1831.

In 1677 Sir Thomas Grosvenor wed Mary Davies. Her dowry included Template:Convert to the west of what was then the boundary of London.^[4]

The subsidiary titles are: Marquess of Westminster (created 1831), Earl Grosvenor (1784), Viscount Belgrave, of Belgrave in the County of Chester (1784), and Baron Grosvenor, of Eaton in the County of Chester (1761). The Dukedom and Marquessate are in the Peerage of the United Kingdom; the rest are in the Peerage of Great Britain. The courtesy title of the eldest son and heir to the Duke is Earl Grosvenor.
