Dickson or, as is common in England, "Dixon," is a patronymic surname, traditionally Scottish and thought to have originated upon the birth of the son of Richard Keith, son of Hervey de Keith, Earl Marischal of Scotland, and Margaret, daughter of the 3rd Lord of Douglas.
 "Nisbet in his Heraldry (Edinburgh 1722) says 'The Dicksons are descendants from Richard Keith, said to be a son of the family of Keith, Earls Marischals of Scotland' and in proof thereof carry the chief of Keith Marischal.
 This Richard was commonly called Dick and the 'son' was styled after him.
 The affix of son in the Lowlands answering the prefix Mac in the Highlands."
 As a result, Clan Dickson is considered a sept of Clan Keith.
 Richard Keith's son, Thomas, took the surname "Dickson," meaning "Dick's son" or "Richard's son."
 Thomas Dickson (1247–1307) himself has quite a history.

Emmett Louis Till (July 25, 1941 – August 28, 1955) was a 14-year-old African-American who was lynched in Mississippi in 1955, after a white woman said she was offended by him in her family's grocery store.

 Till posthumously became an icon of the Civil Rights Movement.
The Forrest River massacre, or Oombulgurri massacre, is a disputed account of a massacre of Indigenous Australian people by a law enforcement party in the wake of the killing of a pastoralist, which took place in the Kimberley region of Western Australia in 1926.

 Charges were brought against two officers but dismissed for lack of evidence.
