Sir Angus James Bruce Ogilvy, (14 September 1928 – 26 December 2004) was a British businessman, best known as the husband of Princess Alexandra, a first cousin of Queen Elizabeth II.
Alexander Stewart, 2nd Earl of Buchan was the only son of James Stewart, 1st Earl of Buchan, and Margaret Ogilvy.
 Alexander succeeded to the Earldom and the Barony of Kingedward and other lands, probably in 1499, as he got sasine of the Earldom on 23 January 1499/1500.
 On 21 January 1490/1491 he got from his father a Charter to himself and his first wife, Isobel Ogilvy, of the lands of the Barony of Kettins and others; and on 6 February 1499/1500, another of the same lands to himself and his second wife, Margaret Ruthven.
Thatched House Lodge is a Grade II-listed building, dating from the 17th century, in Richmond Park in the London Borough of Richmond upon Thames in London, England.
 It was the home of British Prime Minister Sir Robert Walpole and, since 1963, has been a royal residence, being leased from the Crown Estate by Princess Alexandra, The Honourable Lady Ogilvy (born Princess Alexandra of Kent) and, until his death in 2004, her husband Sir Angus Ogilvy.
In discussing consanguineal kinship in anthropology, a parallel cousin or ortho-cousin is a cousin from a parent's same-sex sibling, while a cross cousin is from a parent's opposite-sex sibling.
 So a parallel cousin is the child of the father's brother (paternal uncle's child) or of the mother's sister (maternal aunt's child), while a cross cousin is the child of the mother's brother (maternal uncle's child) or of the father's sister (paternal aunt's child).
 Where there are unilineal descent groups in a society (i.e. matrilineal and/or patrilineal), one's parallel cousins on one or both sides will belong to one's own descent group, while cross cousins will not (assuming descent group exogamy).
James Robert Bruce Ogilvy (born 29 February 1964) is the elder child and only son of Sir Angus Ogilvy and Princess Alexandra.
James Aird Nesbitt (March, c.1907 – November 14, 1985) was a Canadian department store owner.

 Known as Aird, when his father purchased Ogilvy's Department Store on Saint Catherine Street in downtown Montreal in 1927, the twenty-year-old Aird Nesbitt took over management of the store.
 He proved to be a very capable merchandiser whose marketing skills made Ogilvy's one of Montreal's most popular stores.

The Royal House of Boureh Gnilane Joof (variation : Mbin Boureh Gnilane in Serer) was a royal house founded in the 14th century by Jaraff Boureh Gnilane Joof (var : "Bouré Gnilane Diouf" or "Buré Ñilaan").
 He was a member the Serer tribe, from the pre-colonial Kingdom of Sine now part of independent Senegal.
 It was the first royal house founded by the Joof family during the Guelowar period (1350 - 1969).
 Boureh Gnilane Joof was a royal prince and a Jaraff (var : "Diaraf"), a with the powers of a Prime Minister.
 He was neither a Maad a Sinig (king of Sine) nor a Maad Saloum (king of Saloum) but a royal prince who had the title "Jaraff" bestowed upon him by his cousin and brother-in-law - Maad a Sinig Diessanou Faye (king of Sine).
 His father Maad Patar Kholleh Joof (the conqueror) was the king of Laa and Teigne of Baol (king of Baol).
 Boureh's brothers were the first from this house to have succeeded to the throne of Sine during the Guelowar period.
 His name was adopted in his honour to refer to the first royal house founded by the Joof family during this dynastic period.
 The Joof family of Sine, from this royal house also ruled in the Kingdom of Saloum (the Joof paternal dynasty of Sine and Saloum) The Joof family also ruled in Baol (the Joof paternal dynasty of Baol).
 From the date of its foundation up to the abolition of the Serer monarchies of Sine and Saloum in 1969, at least ten kings from this house had succeeded to the throne of Sine.
 As the first royal house of Sine founded by the Joof family in this dynastic period, the Royal House of Boureh Gnilane Joof holds great significance in Senegambian, Joof family and , because all the subsequent royal houses founded by the Joof family (who ruled in three Senegambian kingdoms) branched out from this royal house.
