The Rothschild banking family of England was founded in 1798 by Nathan Mayer von Rothschild (1777–1836) who first settled in Manchester but then moved to London.
 Nathan was sent there from his home in Frankfurt by his father, Mayer Amschel Rothschild (1744–1812).
 Wanting his sons to succeed on their own and to expand the family business across Europe, Mayer Amschel Rothschild had his eldest son remain in Frankfurt, while his four other sons were sent to different European cities to establish a financial institution to invest in business and provide banking services.
 Nathan Mayer von Rothschild, the third son, first established a textile jobbing business in Manchester and from there went on to establish N M Rothschild & Sons bank in London.
The home counties are the counties of England that surround London (although several of them do not border it).
 The counties generally included in the list are Berkshire, Buckinghamshire, Essex, Hertfordshire, Kent, Surrey, and Sussex.
 Other counties more distant from London—such as Bedfordshire, Cambridgeshire, Hampshire and Oxfordshire—are also sometimes regarded as home counties due to their proximity to London and their connection to the London regional economy.
The last member of the Rothschild family to own Waddesdon was James de Rothschild (1878–1957).
 He bequeathed the house and its contents to the National Trust.
 It is now managed by the Rothschild Foundation chaired by Jacob Rothschild, 4th Baron Rothschild.
 It is one of the National Trust's most visited properties, with over 390,000 visitors annually.
 Waddesdon Manor won Visit England's Large Visitor Attraction of the Year category in 2017.
The Home Counties Brigade was an administrative formation of the British Army from 1948 to 1968.

The 1978–79 Home Counties League season was the first in the history of the Combined Counties Football League, a football competition in England, which operates at levels 9–10 of the English football league system.
 This was the only season in which the "Home Counties League" name was used before the league was renamed as the Combined Counties League.
David Mayer de Rothschild (born 25 August 1978) is a British adventurer, ecologist, and environmentalist and head of Sculpt the Future Foundation, a charity that supports innovations and creativity in social and environmental impact efforts.
 He is a member of the Rothschild family, the youngest of three children of Victoria Lou Schott (born 1949) and Sir Evelyn de Rothschild (b. 1931) of the Rothschild banking family of England.
 His middle name "Mayer" is taken from the name of the founder of the Rothschild family banking empire, Mayer Amschel Rothschild.
A Home Counties cricket team was a cricket team formed of players who represented counties which were considered a part of England's home counties.
 The team first appeared in 1862 in a minor match against Southgate Cricket Club.
 The team later appeared once in first-class cricket in 1899 against The Rest at the Central Recreation Ground, Hastings.
 The team for their only first-class match consisted of Arthur Turner and Sailor Young of Essex; Alec Hearne and Bill Bradley of Kent; Francis Ford and Andrew Stoddart of Middlesex; Bobby Abel, Tom Hayward and Digby Jephson of Surrey and; Harry Butt and K. S. Ranjitsinhji of Sussex.
 With the exception of Jephson and Turner, all had played Test cricket for England.
 Their only appearance in first-class cricket ended as a draw.
 The team reappeared in the 1940s, playing two minor matches against Lancashire in 1946 and 1948.
The Rothschild family is a wealthy family descending from Mayer Amschel Rothschild, a court Jew to the German Landgraves of Hesse-Kassel in the Free City of Frankfurt, who established his banking business in the 1760s.
 Unlike most previous court Jews, Rothschild managed to bequeath his wealth and established an international banking family through his five sons, who established themselves in London, Paris, Frankfurt, Vienna, and Naples.
The 2nd Home Counties Division was a 2nd Line Territorial Force division of the British Army in World War I.
 The division was formed as a duplicate of the 44th (Home Counties) Division in November 1914.
 As the name suggests, the division recruited in the Home Counties, particularly Kent, Middlesex, Surrey and Sussex.
 In August 1915, in common with all Territorial Force divisions, it was numbered as 67th (2nd Home Counties) Division.
 Between September 1917 and the end of the year, the division was extensively reorganized and lost its territorial identity; henceforth it was known as 67th Division.
Of all the landowners in the Home counties, particularly the Buckinghamshire area, none has had more impact on the landscape than the Rothschild family.
