Question: In what year was Clara Clemens first husband born?
Context: Yang Xianrong (羊獻容) (died 322), formally (as honored by Han Zhao) Empress Xianwen (獻文皇后, literally "the wise and civil empress") was an empress—uniquely in the history of China, for two different empires and two different emperors.  Her first husband was Emperor Hui of Jin, and her second husband was Liu Yao of Han Zhao.  Also unique was the fact that she was deposed four and restored four times as the empress of Jin (five, if one counts a brief usurpation by Sima Lun against her husband in 301). Violet Emily Wegner, (1887-1960), was the daughter of an Extradition Department detective of Scotland Yard, William T. Wegner, and Arabella Eliza née Darby, who resided in a district of London called Tulse Hill.  Violet made a career in the music halls from the age of 15.  She became known as the "Idol of Berlin".  In 1912, Violet married her first husband, Sergio Francesco Enrico Maria Brunetta d'Usseaux (born 3 March 1885, Torino, Italy), in London.  Sergio's parents were Comte Eugenio Brunetta d'Usseaux and the Russian Countess Zeiffart.  Eugenio was Secretary General of the Olympic Committee that administered the 1908 London Olympics.  Eugenio died in 1919 in mysterious circumstances.  The fate of his son, and Violet's husband, is also unknown although it is suggested he may have been the son Eugenio was trying to reach following the October Revolution.  Whilst traveling in Italy during 1918, Violet met the youngest son and royal prince, Pierre Petrović-Njegoš, of the exiled King Nicholas I of Montenegro.  After some delay, it is said, at the behest of Violet's mother who advised them to await the award of monies claimed by the prince from the new Yugoslav government for the confiscation of his family's property in Montenegro, Violet married Prince Pierre (Peter) of Montenegro in Paris in the April of 1924.  Violet then became HRH Princess Pierre of Montenegro and thus sister-in-law to Queen Elena of Italy as well as a host of other European princes and kings via her husband's siblings. Marilyn: The Untold Story is a 1980 television film, about the life of the 1950s sex symbol-movie star, Marilyn Monroe.

Letters from the Earth is a posthumously published work of celebrated American author Mark Twain (1835–1910).  It comprises essays written during a difficult time in Twain's life (1904–09), when he was deeply in debt and had recently lost his wife and one of his daughters.  The content concerns morality and religion and strikes a sarcastic — Twain's own term throughout the book — tone.  Initially, another of his daughters, Clara Clemens, objected to its publication in March 1939, probably because of its controversial and iconoclastic views on religion, claiming it presented a ""distorted"" view of her father.  Henry Nash Smith helped change her position in 1960.  Clara explained her change of heart in 1962 saying that ""Mark Twain belonged to the world"" and that public opinion had become more tolerant.  She was also influenced to release the papers by her annoyance with Soviet reports that her father's ideas were being suppressed in the United States.  The papers were selected, edited and sequenced for the book in 1939 by Bernard DeVoto. Martha Wayles Skelton Jefferson (born Martha Wayles; October 30, 1748 – September 6, 1782) was the wife of Thomas Jefferson.  She was a widow at her second wedding, as her first husband had died young.  When her second husband, Jefferson, was Governor of Virginia, she served as First Lady of Virginia from 1779 to 1781.  She would have been the third First Lady of the United States, but she died in 1782 well before her husband Thomas Jefferson's presidential term from 1801 to 1809.  She also died before the United States Constitution was adopted. Ossip Gabrilowitsch (Осип Сoломонович Габрилович, "Osip Solomonovich Gabrilovich"; he used the German transliteration "Gabrilowitsch" in the West) (7 February [O.S. 26 January] 1878 14 September 1936) was a Russian-born American pianist, conductor and composer. Margaret de Quincy, 2nd Countess of Lincoln "suo jure" (c. 1206 – March 1266) was a wealthy English noblewoman and heiress having inherited in her own right the Earldom of Lincoln and honours of Bolingbroke from her mother Hawise of Chester, received a dower from the estates of her first husband, and acquired a dower third from the extensive earldom of Pembroke following the death of her second husband, Walter Marshal, 5th Earl of Pembroke.  Her first husband was John de Lacy, 2nd Earl of Lincoln, by whom she had two children.  He was created 2nd Earl of Lincoln by right of his marriage to Margaret.  Margaret has been described as "one of the two towering female figures of the mid-13th century". Robert FitzStephen (died 1183) was a Cambro-Norman soldier, one of the leaders of the Norman invasion of Ireland, for which he was granted extensive lands in Ireland.  He was a son of the famous Nest, daughter of Rhys ap Tewdwr, the last king of Deheubarth (South Wales).  His father was Nest's second husband, Stephen, Constable of Cardigan (Welsh: "Aberteifi" ).  Following the death of her first husband, Gerald de Windsor, her sons had married her to Stephen, her husband's constable for Cardigan.  By Stephen, she had another son, possibly two; the eldest was Robert, and the younger may have been Hywel. Clara Langhorne Clemens Samossoud, formerly Clara Langhorne Clemens Gabrilowitsch (June 8, 1874 – November 19, 1962), was the daughter of Samuel Clemens, who wrote as Mark Twain.  She was a contralto concert singer and, as her father's only surviving child, managed his estate and guarded his legacy after his death.  She was married twice—first to Ossip Gabrilowitsch, then (after Gabrilowitsch's death) to Jacques Samossoud.  She wrote biographies of Gabrilowitsch and of her father.  In her later life she became a Christian Scientist. In 1884, author and journalist Samuel Clemens, popularly known as Mark Twain, founded the subscription publishing firm of Charles L. Webster and Company.  The firm was named after Clemens' niece’s husband Charles L. Webster whom Clemens appointed the firm's business director.  The formation of the company came out of Clemens' dissatisfaction with his previous publishers including Charles H. Webb, Elisha Bliss, and James R. Osgood.  Clemens wanted to earn a dual income as both author and publisher of books.  The first two American publications of the firm, "Adventures of Huckleberry Finn" (1885) and the "Personal Memoirs of Ulysses S. Grant" (1885) were highly successful.  The Ulysses S. Grant memoir publication in particular financially helped Grant and his family at a time when Grant was sick having been diagnosed with throat cancer.  Grant was former President of the United States and top commanding general during the Civil War and Reconstruction.  After Grant died, Clemens gave Grant's widowed wife, Julia, a substantial record royalty check of $200,000 dollars.  According to Webster, prior to his death, Grant dictated the last part of the second volume to a stenographer working for the firm, due to writing fatigue, starting with Robert E. Lee's surrender at Appomattox.  Webster, who accompanied the stenographer, respected Grant's reputation and honored Grant's request to keep secret from reporters that Grant dictated part of the book.
