Background: Donatien Alphonse Francois, Marquis de Sade (2 June 1740 - 2 December 1814) (French: [maRki d@ sad]), was a French nobleman, revolutionary politician, philosopher, and writer, famous for his libertine sexuality. His works include novels, short stories, plays, dialogues, and political tracts; in his lifetime some were published under his own name, while others appeared anonymously, of which Sade denied being the author. Sade is best known for his erotic works, which combined philosophical discourse with pornography, depicting sexual fantasies with an emphasis on violence, criminality, and blasphemy against Christianity.
Context: Donatien Alphonse Francois de Sade was born on 2 June 1740, in the Hotel de Conde, Paris, to Jean Baptiste Francois Joseph, Count de Sade and Marie Eleonore de Maille de Carman, cousin and Lady-in-waiting to the Princess of Conde. He was his parents' only surviving child. He was educated by an uncle, the Abbe de Sade. In Sade's youth, his father abandoned the family; his mother joined a convent. He was raised with servants who indulged "his every whim," which led to his becoming "known as a rebellious and spoiled child with an ever-growing temper."  Later in his childhood, Sade was sent to the Lycee Louis-le-Grand in Paris, a Jesuit college, for four years. While at the school, he was tutored by Abbe Jacques-Francois Amblet, a priest. Later in life, at one of Sade's trials the Abbe testified, saying that Sade had a "passionate temperament which made him eager in the pursuit of pleasure" but had a "good heart." At the Lycee Louis-le-Grand, he was subjected to "severe corporal punishment," including "flagellation," and he "spent the rest of his adult life obsessed with the violent act." At age 14, Sade began attending an elite military academy.  After 20 months of training, on 14 December 1755, at age 15, Sade was commissioned as a sub-lieutenant, becoming a soldier. After 13 months as a sub-lieutenant, he was commissioned to the rank of cornet in the Brigade de S. Andre of the Comte de Provence's Carbine Regiment. He eventually became Colonel of a Dragoon regiment and fought in the Seven Years' War. In 1763, on returning from war, he courted a rich magistrate's daughter, but her father rejected his suitorship and instead arranged a marriage with his elder daughter, Renee-Pelagie de Montreuil; that marriage produced two sons and a daughter. In 1766, he had a private theatre built in his castle, the Chateau de Lacoste, in Provence. In January 1767, his father died.
Question: Did he have siblings?
Answer: He was his parents' only surviving child.

Problem: Background: Scott W. Rothstein (born June 10, 1962) is a disbarred lawyer and the former managing shareholder, chairman, and chief executive officer of the now-defunct Rothstein Rosenfeldt Adler law firm. He was accused of funding his philanthropy, political contributions, law firm salaries, and an extravagant lifestyle with a $1.2 billion Ponzi scheme, one of the largest such in history. On December 1, 2009, Rothstein turned himself in to authorities and was subsequently arrested on charges related to the Racketeer Influenced and Corrupt Organizations Act (RICO). Although his arraignment plea was not guilty, Rothstein cooperated with the Government and reversed his plea to guilty of five federal crimes on January 27, 2010.
Context: Debra Villegas, who handles his money, is the law firm's chief operating officer. She is co-owner with Rothstein in a home at 2307 Castilla Isle, as of May 2009. According to records, Rothstein originally purchased the property in September 2007, for $1.75 million, and sold it for $10 to a shell corporation in September 2009.  In 2005, the year the Ponzi scheme allegedly began, Villegas earned $80,000 a year. In 2007, her salary had increased to $145,000. Villegas received two Swiss watches -- a Rolex and a Breitling -- from her "employer". Rothstein paid off her couch and a bedroom set and held title to her two Honda water scooters. Villegas was living in a $475,000 Weston home that Rothstein signed over to her in July 2009 for $100 and "love and affection," according to the deed. Villegas registered a 2009 $100,000 Maserati GranTurismo at the home in January, 2009. In November 2009, Federal prosecutors seized the home, alleging that it was among Rothstein's ill-gotten assets.  Villegas' estranged husband, Tony Villegas, was charged on circumstantial evidence in the March 2008 murder in Plantation, Florida of Melissa Britt Lewis, a partner in Rothstein's firm. Although early news reports wondered at whether the evidence was substantial, according to New Times, "Nine days later, forensic testing revealed that Tony's DNA had been found on Melissa's suit jacket - the same jacket she wore on the day she died."  Police sealed the arrest affidavit. As a result of the homicide and the nature of the legal business, Rothstein has a team of "executive protection specialists" to guard the firm and his family, his teen-aged daughter. The prosecutor who had first worked on the Villegas case, Howard Scheinberg, went to work for Rosenfeldt Rothstein Adler. Villegas, a train conductor, remains in jail awaiting trial. The motive was supposedly revenge for Lewis's closeness with Debra. Debra and Melissa share a therapist: Ilene Vinikoor, whose husband, David represents general counsel, David Boden in the Ponzi scheme investigation.  "You get anger from people... 'that prick from the Bronx. They say I'm building the law firm too fast, that it must be a house of cards."

Rothstein has a team of "executive protection specialists" to guard the firm and his family, his teen-aged daughter.
