Laurence Edward Adams (born 14 February 1931) is an English former footballer, who played for Watford as an inside left.
 Born in Barnet (then part of Hertfordshire), he made his sole Football League appearance while doing his National Service.
 Under the management of Haydn Green, Adams played a full match on 23 February 1952, as Watford defeated Walsall 2–0 in front of a crowd of 8,909 at Vicarage Road.
 He turned professional upon leaving the army, but did not play another senior game, and left the club at the end of the 1952–53 season.
 Although at that time professional players were not normally allowed to play amateur football again, Adams subsequently played for Whipton as a permit player in 1955.
The 2008-09 National Division Two was the ninth and final version (twenty second overall) of the third division of the English rugby union league system using the name National Division Two.
 The RFU was planning to introduced a new professionalized format of the second division for the 2009-10 season which would lead to widespread league changes throughout the English league system including National Two being renamed National One and being increased from the 14 teams to 16 teams – a decision they made halfway through the season (more information on these changes is provided in the Divisional Changes section below).
 New teams to the division included Birmingham & Solihull (known the following season as Pertemps Bees) and Launceston who were relegated from the 2007–08 National Division One while promoted teams included Tynedale coming up from the 2007–08 National Division Three North while Mounts Bay (champions) and Cinderford (playoffs) both from the 2007–08 National Division Three South.
Watford Football Club is a professional football club based in Watford, Hertfordshire, England, that plays in the Premier League, the highest level in the English football league system.
 Founded in 1881 as Watford Rovers, the club entered the FA Cup for the first time in 1886, and the Southern League a decade later.
 After finishing the 1914–15 season as Southern League champions under the management of Harry Kent, Watford joined the Football League in 1920.
 The club played at several grounds in its early history, before moving to a permanent location at Vicarage Road in 1922, where it remains to this day.
 Watford spent most of the following half century in the lower divisions of The Football League, changing colours and crest on multiple occasions.
The 2000–01 National Division Two was the fourteenth full season of rugby union within the third tier of the English league system currently known as National League 1.
 New teams to the division included West Hartlepool and Rugby Lions who were relegated from the 1999–2000 Allied Dunbar Premiership Two while promoted teams included Kendal and Esher who were promoted as champions of National Division Three North and National Division Three South respectively.
 The league system was 2 points for a win and 1 point for a draw.
Gillingham Football Club is an English professional association football club based in Gillingham, Kent, playing in Football League One, the third level of the English football league system, as of the 2013–14 season.
 The club was formed in 1893 as New Brompton F.C., a name which was retained until 1912, and has played home matches at Priestfield Stadium throughout its history.
 The club joined the Football League in 1920, was voted out of the league in favour of Ipswich Town at the end of the 1937–38 season, but returned to the league 12 years later after it was expanded from 88 to 92 clubs.
 Between 2000 and 2005, Gillingham played in the second tier of the English league for the only time in the club's history, achieving a highest league finish of eleventh place in 2002–03.
The Welsh Premier League (Welsh: "Uwch Gynghrair Cymru" ) is an association football league based in Wales.
 Formed in 1992 as the League of Wales, a name it retained until 2002, it was the first national football league in the country.
 In its inaugural season 20 teams played in the league, but it has since been significantly restructured and has 12 member clubs in the 2013–14 season.
 Although it is the highest level of the Welsh football league system, the Welsh Premier League has never included the country's professional clubs, Cardiff City, Swansea City, Wrexham and Newport County.
 For historical reasons these clubs all play within the English league system.
 Instead the Welsh Premier League consists primarily of clubs from small towns and villages and the majority of the players are semi-professional.
 As of 2013, The New Saints, who have played in Oswestry in England since 2005, were the only full-time professional team in the league.
Cardiff City Football Club, a professional association football club based in Cardiff, Wales, was founded in 1899 as Riverside A.F.C. by members of Riverside Cricket Club.
 The club's first year was made up of friendlies before they were admitted to the Cardiff & District League in 1900 and later the South Wales Amateur League in 1907.
 The following year, the club were granted permission to adopt the name Cardiff City, having been denied the previous year as they were deemed not to be playing at a high enough level, and moved into the English football league system for the first time by joining Division Two of the Southern Football League.
 They won promotion to Division One in the 1912–13 season and remained there until 1920, playing just three seasons during this time due to the outbreak of the First World War when league football was abandoned.
 In 1920, they were elected to The Football League, joining the Second Division for one season, winning promotion in their first season after finishing second.
 The club also competed regularly in the Welsh Cup, winning the trophy 22 times during their history, second only to Wrexham's 23, before they were denied entrance into the competition from 1995 onward by the Football Association of Wales, along with all other clubs playing in the English league pyramid.

Barnes Rugby Football Club, formerly known simply as the Barnes Club, is a rugby union club which is claimed by some sources to be the world's first and oldest club in any code of football.
 It is claimed that Barnes RFC was founded in as early as 1839 but there is no actual evidence, so the club itself states to have clear documents about its activities from the 1920s.
 If the claim is true, then Barnes is the world's oldest football club in all codes.
 The club, from Barnes, London, also played a major role in the early years of association football, and was one of the teams in the first ever game of football.
 The club currently play in the fifth tier of the English league system, London & South East Premier.
