Answer the question at the end by quoting:

Zelda Fitzgerald (nee Sayre; July 24, 1900 - March 10, 1948) was an American socialite, novelist, painter and wife of author F. Scott Fitzgerald. Born in Montgomery, Alabama, she was noted for her beauty and high spirits, and was dubbed by her husband as "the first American Flapper". She and Scott became emblems of the Jazz Age, for which they are still celebrated. The immediate success of Scott's first novel This Side of Paradise (1920) brought them into contact with high society, but their marriage was plagued by wild drinking, infidelity and bitter recriminations.
Born in Montgomery, Alabama, Zelda Sayre was the youngest of six children. Her mother, Minerva Buckner "Minnie" Machen (November 23, 1860 - January 13, 1958), named her after characters in two little-known stories: Jane Howard's "Zelda: A Tale of the Massachusetts Colony" (1866) and Robert Edward Francillon's "Zelda's Fortune" (1874). A spoiled child, Zelda was doted upon by her mother, but her father, Anthony Dickinson Sayre (1858-1931)--a justice of the Supreme Court of Alabama and one of Alabama's leading jurists--was a strict and remote man.  The family was descended from early settlers of Long Island, who had moved to Alabama before the Civil War. By the time of Zelda's birth, the Sayres were a prominent Southern family. Her great-uncle, John Tyler Morgan, served six terms in the United States Senate; her paternal grandfather edited a newspaper in Montgomery; and her maternal grandfather was Willis Benson Machen, who served a partial term as a U.S. senator from Kentucky. Her siblings were Anthony Dickinson Sayre, Jr. (1894-1933), Marjorie Sayre (Mrs. Minor Williamson Brinson) (1886-1960), Rosalind Sayre (Mrs. Newman Smith) (1889-1979), Clothilde Sayre (Mrs. John Palmer) (1891-1986), and Lenora Sayre (1897-1899), who died of diphtheria at age two.  As a child, Zelda Sayre was extremely active. She danced, took ballet lessons and enjoyed the outdoors. In 1914, Sayre began attending Sidney Lanier High School. She was bright, but uninterested in her lessons. Her work in ballet continued into high school, where she had an active social life. She drank, smoked and spent much of her time with boys, and she remained a leader in the local youth social scene. A newspaper article about one of her dance performances quoted her as saying that she cared only about "boys and swimming." She developed an appetite for attention, actively seeking to flout convention--whether by dancing the Charleston, or by wearing a tight, flesh-colored bathing suit to fuel rumors that she swam nude. Her father's reputation was something of a safety net, preventing her social ruin, but Southern women of the time were expected to be delicate, docile and accommodating. Consequently, Sayre's antics were shocking to many of those around her, and she became--along with her childhood friend and future Hollywood starlet Tallulah Bankhead--a mainstay of Montgomery gossip. Her ethos was encapsulated beneath her high-school graduation photo:  Why should all life be work, when we all can borrow?  Let's think only of today, and not worry about tomorrow.

Did she have siblings?

Zelda Sayre was the youngest of six children.

IN: Edgar Yipsel "Yip" Harburg (born Isidore Hochberg, Yiddish: ysydvr hvkbrg; April 8, 1896 - March 5, 1981) was an American popular song lyricist who worked with many well-known composers. He wrote the lyrics to the standards "Brother, Can You Spare a Dime?"

Harburg, the youngest of four surviving children (out of ten), was born Isidore Hochberg on the Lower East Side of New York City on April 8, 1896. His parents, Lewis Hochberg and Mary Ricing, were Yiddish-speaking Orthodox Jews who had emigrated from Russia.  He later adopted the name Edgar Harburg, and came to be best known as Edgar "Yip" Harburg. He attended Townsend Harris High School, where he and Ira Gershwin, who met over a shared fondness for Gilbert and Sullivan, worked on the school paper and became lifelong friends. According to his son Ernie Harburg, Gilbert and Irish dramatist George Bernard Shaw taught his father, a "democratic socialist, [and] sworn challenger of all tyranny against the people, that 'humor is an act of courage' and dissent".  After World War I, Harburg returned to New York and graduated from City College (later part of the City University of New York), which Ira Gershwin had initially attended with him, in 1921. After Harburg married and had two children, he started writing light verse for local newspapers. He became a co-owner of Consolidated Electrical Appliance Company, but the company went bankrupt following the crash of 1929, leaving Harburg "anywhere from $50,000 - $70,000 in debt," which he insisted on paying back over the course of the next few decades. At this point, Harburg and Ira Gershwin agreed that Harburg should start writing song lyrics.  Gershwin introduced Harburg to Jay Gorney, who collaborated with him on songs for an Earl Carroll Broadway review (Earl Carroll's Sketchbook): the show was successful and Harburg was engaged as lyricist for a series of successful revues, including Americana in 1932, for which he wrote the lyrics of "Brother, Can You Spare a Dime?" to the tune of a lullaby Gorney had learned as a child in Russia. This song swept the nation, becoming an anthem of the Great Depression.  Harburg was a staunch critic of religion and an atheist. He wrote a poem entitled "Atheist" that summarized his views on god and religion.

Was Harburg religious?
