Answer the question at the end by quoting:

James Black was born in Hackensack, New Jersey on 1 May 1800. James' mother died when he was very young and he had difficulty getting along with his stepmother. Black ran away from home to Philadelphia, Pennsylvania at age 8 and was apprenticed to a silversmith. At age 18 he migrated westward and took jobs on the Ohio and Mississippi rivers.
During his travels, Black had befriended Elijah Stuart. Stuart opened a tavern at Washington and Black was hired by a local blacksmith named William Shaw. Black, due to his previous training, worked on firearms and knives while Shaw concentrated on horse shoes, wagon wheels, and the like. Black would later become a partner in the business with Shaw. Stuart's tavern would become famous as the place where Davy Crockett, Jim Bowie, and William B. Travis created the plan for an independent Texas and Black would go on to create some of the world's finest knives. Black fell in love with his partner's daughter, Anne Shaw, and was forced out of the partnership when Shaw would not allow the marriage. Backed by the note he had received from the dissolved partnership Black purchased some land along the Cossatot River and established a blacksmith's shop, dam, and mill.  Black's endeavor came to an end when he was thrown off of his land. Local officials claimed that the land was Indian treaty land and that Black could not legally inhabit it. Black then discovered that the note he had received from William Shaw for his share of the partnership was actually worthless. Black set up his own blacksmithy in competition with Shaw's and married Shaw's daughter in 1828 despite Shaw's objections and also convinced Shaw's son to join him in his business. Black was soon recognized as the best blacksmith in the area which had a bad effect on his father-in-law's competing shop.  Black and his wife had three sons and a daughter during this period: William Jefferson in 1829, Grandison Deroyston in 1830, Sarah Jane in 1832, John Colbert in 1834, and Sydinham James in 1835. Black became a respected member of the community and served in local government posts.

Why would Shaw not allow the marriage?

Backed by the note he had received from the dissolved partnership Black purchased some land along the Cossatot River and established a blacksmith's shop, dam, and mill.

Some context: Lady Antebellum is an American country music group formed in Nashville, Tennessee in 2006. The group is composed of Hillary Scott (lead and background vocals), Charles Kelley (lead and background vocals, guitar), and Dave Haywood (background vocals, guitar, piano, mandolin). Scott is the daughter of country music singer Linda Davis, and Kelley is the brother of pop singer Josh Kelley. The group made its debut in 2007 as guest vocalists on Jim Brickman's single "Never Alone", before signing to Capitol Nashville.
Lady Antebellum was formed in 2006, in Nashville, Tennessee, by Charles Kelley, Dave Haywood, and Hillary Scott. Scott is the daughter of country music singer Linda Davis, best known for her duet vocals on Reba McEntire's 1993 hit "Does He Love You", and Charles Kelley is the brother of pop and country artist Josh Kelley. Hillary Scott attended Donelson Christian Academy in Donelson, Tennessee. Kelley moved to Nashville in mid-2005 from Winston-Salem, North Carolina, where he had been working construction with his brother John. Trying to become a successful solo country artist, Kelley convinced his old middle-school classmate, Haywood, to move to Nashville from Georgia in 2006 so they could write music together. Shortly thereafter, Scott recognized Kelley from Myspace, and they started to talk at a Nashville music club. Kelley invited Scott to join him and Haywood in the new group, which assumed the name Lady Antebellum.  On the BBC Radio 2 Drivetime Show August 9, 2010, the band explained that the name comes from when the group did a photo shoot in historical costumes at antebellum houses. In American history, the Antebellum era commonly refers to the period before the Civil War in the Southern United States. The trio then began performing at local venues in Nashville before being signed in July 2007 to a recording contract with Capitol Records Nashville. In an interview with Sirius Satellite Radio, Scott said she was rejected from auditions for American Idol twice, not even making it past the first round.  The name "Lady Antebellum" has been criticized for glorifying an era of the American South in which society revolved around the institutionalized slavery of black people.
How did they meet
A: Kelley convinced his old middle-school classmate, Haywood, to move to Nashville from Georgia in 2006 so they could write music together.

IN: O'Neill was born in a hotel, the Barrett House, at Broadway and 43rd Street, on what was then Longacre Square (now Times Square). A commemorative plaque was first dedicated there in 1957. The site is now occupied by 1500 Broadway, which houses offices, retail, and ABC Studios. He was the son of Irish immigrant actor James O'Neill and Mary Ellen Quinlan, who was also of Irish descent.

O'Neill was married to Kathleen Jenkins from October 2, 1909 to 1912, during which time they had one son, Eugene O'Neill, Jr. (1910-1950). In 1917, O'Neill met Agnes Boulton, a successful writer of commercial fiction, and they married on April 12, 1918. They lived in a home owned by her parents in Point Pleasant, New Jersey, after their marriage. The years of their marriage--during which the couple lived in Connecticut and Bermuda and had two children, Shane and Oona--are described vividly in her 1958 memoir Part of a Long Story. They divorced in 1929, after O'Neill abandoned Boulton and the children for the actress Carlotta Monterey (born San Francisco, California, December 28, 1888; died Westwood, New Jersey, November 18, 1970). O'Neill and Carlotta married less than a month after he officially divorced his previous wife.  In 1929, O'Neill and Monterey moved to the Loire Valley in central France, where they lived in the Chateau du Plessis in Saint-Antoine-du-Rocher, Indre-et-Loire. During the early 1930s they returned to the United States and lived in Sea Island, Georgia, at a house called Casa Genotta. He moved to Danville, California in 1937 and lived there until 1944. His house there, Tao House, is today the Eugene O'Neill National Historic Site.  In their first years together, Monterey organized O'Neill's life, enabling him to devote himself to writing. She later became addicted to potassium bromide, and the marriage deteriorated, resulting in a number of separations, although they never divorced.  In 1943, O'Neill disowned his daughter Oona for marrying the English actor, director, and producer Charlie Chaplin when she was 18 and Chaplin was 54. He never saw Oona again.  He also had distant relationships with his sons. Eugene O'Neill, Jr., a Yale classicist, suffered from alcoholism and committed suicide in 1950 at the age of 40. Shane O'Neill became a heroin addict and moved into the family home in Bermuda, Spithead, with his new wife, where he supported himself by selling off the furnishings. He was disowned by his father before also committing suicide (by jumping out of a window) a number of years later. Oona ultimately inherited Spithead and the connected estate (subsequently known as the Chaplin Estate). In 1950 O'Neill joined The Lambs, the famed theater club.

Was Jenkins his only spouse?
