Context: Jacqueline Left Hand Bull (formerly Delahunt, born in 1943), member of the Sicangu Lakota of the Rosebud Sioux Tribe, was brought up in her view in a traditional Lakota way by her grandparents and parents.  She became a member of the Bahá'í Faith in 1981, appointed a Continental Counselor in 1988, and was elected as Chair of the National Spiritual Assembly of the Bahá'ís of the United States in 2007.  The family history of the name "Left Hand Bull" involves the elder brother of a family who had done the difficult task of hunting a Buffalo from the left side and was known to provide for more than his family in his hunting.  Years later the younger brother reconnected with the elder and undertook to greatly honor the elder in a ceremony and in return the elder brother traded his name.  She shares a short stature with this younger brother who was given the name "Left Hand Bull". Eberhard III (c. 885 – 2 October 939), a member of the Conradine dynasty, was Duke of Franconia, succeeding his elder brother, King Conrad I, in December 918.  From 926 to 928, he also acted as ruler of Lotharingia. Lord Blayney, Baron of Monaghan, in the County of Monaghan, was a title in the Peerage of Ireland.  It was created in 1621 for the soldier Sir Edward Blayney.  He was succeeded by his son, the second Baron.  He was killed at the Battle of Benburb in 1646.  His younger son, the fourth Baron (who succeeded his elder brother), represented County Monaghan in the Irish House of Commons.  His elder son, the fifth Baron, was attainted by the Parliament of James II for supporting William of Orange.  He had no sons and was succeeded by his younger brother, the sixth Baron.  He was Governor of County Monaghan.  His son, the seventh Baron, was Lord Lieutenant of County Monaghan.  He was succeeded by his elder son, the eighth Baron.  He was a clergyman and served as Dean of Killaloe.  He had no surviving children and was succeeded by his younger brother, the ninth Baron.  He was a Lieutenant-General in the Army.  His younger son, the eleventh Baron (who succeeded his elder brother), was also a Lieutenant-General in the Army and fought in the Peninsular War.  Lord Blayney also represented the rotten borough of Old Sarum in Parliament.  His son, the twelfth Baron, sat as Conservative Member of Parliament for County Monaghan and was later an Irish Representative Peer from 1841 until his death.  On his death in 1874 the title became extinct. In 1763, he entered the House of Commons as Member of Parliament for Brecon, succeeding his elder brother.  He was Bailiff of Brecon in 1768, and a lieutenant in the Foot Guards 1769.  That year he accepted the Stewardship of the Manner of East Hendred to succeed his late father in a by-election at Breconshire, which he represented until his death.  He married Mary, daughter of Thomas Parry and widow of Robert Myners Gough, but had no children by her.  In 1771, he inherited the Tredegar estate from his elder brother, Sir Thomas Morgan, and succeeded him as Lord Lieutenant of Brecknockshire.  The castle on his estates at Rhiperw burned in 1783, and rebuilding was not completed until after his death in 1787.  His estates went to his younger brother, Sir John Morgan.

Baron Middleton, of Middleton in the County of Warwick, is a title in the Peerage of Great Britain.  It was created in 1711 for Sir Thomas Willoughby, 2nd Baronet, who had previously represented Nottinghamshire and Newark in Parliament.  The Willoughby Baronetcy, of Wollaton in the County of Nottingham, had been created in the Baronetage of England in 1677 for his elder brother Francis Willoughby, with special remainder to the latter's only brother Thomas, who succeeded him in 1688.  Lord Middleton was succeeded by his eldest son, the second Baron.  He sat as Member of Parliament for Nottinghamshire and Tamworth.  On the death of his younger son, the fourth Baron (who had succeeded his elder brother), the line of the eldest son of the first Baron failed.  He was succeeded by his cousin Henry Middleton, the fifth Baron.  He was the son of the Hon. Thomas Willoughby (c. 1694–1742), second son of the first Baron.  On the death of his son, the sixth Baron, this line of the family also failed. Ashikaga Tadayoshi (足利 直義 , 1306 - March 13, 1352, Kamakura, Japan) was a general of the Northern and Southern Courts period (1337–92) of Japanese history and a close associate of his elder brother Takauji, the first Muromachi shogun.  Son of Ashikaga Sadauji and Uesugi Kiyoko, daughter of Uesugi Yorishige, the same mother as Takauji, he was a pivotal figure of the chaotic transition period between the Kamakura and Muromachi shogunates.  Tadayoshi is today considered a military and administrative genius and the true architect of many of his elder brother's successes.  In contemporary chronicles he is rarely called with his name, but is instead called either "gosho" (御所 ) or Daikyū-ji-dono (大休寺殿 ) from the name of his family temple.  His posthumous name was Kozan Keigen (古山慧源 ) . Rajendra Chola II reigned as the Chola king succeeding his elder brother Rajadhiraja Chola in the 11th century.  He is best remembered for his role in the battle of Koppam along with his elder brother where he dramatically turned the tables on the Chalukyan King Someshvara I, after the death of his brother in 1052.  During his early reign an expedition was led to Sri Lanka, in the course of which the Sri Lanka army was routed and their king Vijayabahu I of Polonnaruwa was driven to take refuge in a mountain-fortress.  He maintained the Chola Empire well as the distribution of his records show that the Chola Empire did not suffer any loss of territory during his reign. Matilda of Franconia (  1027 – 1034) was a daughter of Emperor Conrad II and Gisela of Swabia from the Salian dynasty.  Matilda’s elder brother was Henry III, Holy Roman Emperor. The Song of the Xianbei Brother () is a popular song of the Xianbei people composed by Murong Wei in 285 AD.  It is preserved in Chinese translation and is about the Xianbei chief's regrets for having sent his brother away to the West.  The original Chinese translation left the Xianbei word for elder brother ("A-kan") in the title, which is identical to the Mongolic word for elder brother ("Aqan" or "Aghan").  The same word exists in Turkic and Tungusic languages, but the Xianbei are generally considered Mongolic peoples.  This would make the song one of the earliest attestations of a Mongolic language.  The song was first translated into English in 1939.
