Context paragraphs:
Kenneth Hutchings: Kenneth Lotherington Hutchings (7 December 1882 – 3 September 1916) was an English amateur cricketer who played for Kent County Cricket Club and the England cricket team between 1902 and 1912.  He was primarily a batsman who played a major role in three of Kent's County Championship wins in the years before World War I and who played seven Test matches for England.  He was chosen as one of Wisden's Cricketers of the Year in 1907.  Hutchings was killed in action during the Battle of the Somme whilst serving with the King's Liverpool Regiment in 1916.

Rowena: Rowena in the Matter of Britain was the daughter of the mythological Anglo-Saxon chief Hengist and wife of Vortigern, "King of the Britons".  Presented as a beautiful "femme fatale", she won her people the Kingdom of Kent through her treacherous seduction of Vortigern.  Contemporary sources do not mention Rowena, which leads modern historians to regard her as fictitious.

Princess Michael of Kent: Princess Michael of Kent (née Baroness Marie Christine von Reibnitz; born 15 January 1945) is a member of the British Royal Family of German and Hungarian descent.  She is married to Prince Michael of Kent, a grandson of King George V.  Princess Michael was an interior designer before becoming an author; she has written several books on European royalty (mostly her cousins).  She also undertakes lecture tours as well as supporting her husband in his public duties.

Octa of Kent: Octa (or Octha) (c. 500 – 543) was an Anglo-Saxon King of Kent during the 6th century.  Sources disagree on his relationship to the other kings in his line; he may have been the son of Hengist or Oisc, and may have been the father of Oisc or Eormenric.  The dates of his reign are unclear, but he may have ruled from 512 to 534 or from 516 to 540.  Despite his shadowy recorded history Octa made an impact on the Britons, who describe his deeds in several sources.

Thomas Middleton: Thomas Middleton (baptised 18 April 1580 – July 1627) was an English Jacobean playwright and poet.  Middleton stands with John Fletcher and Ben Jonson among the most successful and prolific playwrights who wrote their best plays during the Jacobean period.  He was one of the few Renaissance dramatists to achieve equal success in comedy and tragedy.  Also a prolific writer of masques and pageants, he remains one of the most notable and distinctive of Jacobean dramatists.

Eadbald of Kent: Eadbald (Old English: "Ēadbald" ) was King of Kent from 616 until his death in 640.  He was the son of King Æthelberht and his wife Bertha, a daughter of the Merovingian king Charibert.  Æthelberht made Kent the dominant force in England during his reign and became the first Anglo-Saxon king to convert to Christianity from Anglo-Saxon paganism.  Eadbald's accession was a significant setback for the growth of the church, since he retained his people's paganism and did not convert to Christianity for at least a year, and perhaps for as much as eight years.  He was ultimately converted by either Laurentius or Justus, and separated from his first wife, who had been his stepmother, at the insistence of the church.  Eadbald's second wife was Emma, who may have been a Frankish princess.  She bore him two sons, Eormenred and Eorcenberht, and a daughter, Eanswith.

Tommy Norment: Thomas Kent "Tommy" Norment Jr. (born April 12, 1946, in Richmond, Virginia) is the current Republican Majority Leader of the Senate of Virginia.

He represents the 3rd senatorial district of the Virginia Senate, which includes parts of the Virginia Peninsula, plus King and Queen County, King William County, New Kent County and Gloucester County on the Middle Peninsula.

Hengist, King of Kent: Hengist, King of Kent, or The Mayor of Quinborough is a Jacobean stage play by Thomas Middleton, first published in 1661.

William Hammond (cricketer): William Hammond was a nineteenth century cricketer who briefly played first-class cricket for Kent and a Gentlemen of Kent and Surrey XI between 1855 and 1857, before emigrating to the United States where he played cricket for over ten years until 1868.  Born in Maidstone, Kent, Hammond was a batsman of unknown handedness who debuted at Lord's in July 1855 with two single-figure scores against a Gentleman of England XI.  He represented the Gentlemen of Kent and Surrey again in August that same year, making two scores of seven.  He then went on to make his only appearance for Kent in June 1857 where he made his career best score of 17 against Surrey.

Paul Nixon: Paul Andrew Nixon (born 21 October 1970) is a former English cricketer who played for Leicestershire, England, England A, MCC and Kent.  He is a wicket-keeper and left-handed batsman.  He announced that he would play his final game of professional cricket at Grace Road against Kent on 6 August 2011 in a T20 quarter final, which meant that should Leicestershire beat Kent and get into finals day he would play.  Leicestershire got into finals day, having had to achieve their highest ever T20 chase of 203 in 20 overs, which they managed in 19.2 overs, with Nixon scoring 31 runs from 17 deliveries.  Leicestershire then went on to win the competition; firstly beating Lancashire in a super over eliminator, then beating Somerset by 18 runs in the final, meaning that Nixon got the fairytale end to his career that he dreamed of.  His retirement on 27 August 2011 marked the end of his 23-year career.
