Background: David "Davy" Crockett (August 17, 1786 - March 6, 1836) was a 19th-century American folk hero, frontiersman, soldier, and politician. He is commonly referred to in popular culture by the epithet "King of the Wild Frontier". He represented Tennessee in the U.S. House of Representatives and served in the Texas Revolution. Crockett grew up in East Tennessee, where he gained a reputation for hunting and storytelling.
Context: Crockett fell in love with John Canady's niece Amy Summer, who was engaged to Canady's son Robert. While serving as part of the wedding party, Crockett met Margaret Elder. He persuaded her to marry him, and a marriage contract was drawn up on October 21, 1805. Margaret had also become engaged to another young man at the same time and married him instead.  He met Polly Finley and her mother Jean at a harvest festival. Although friendly towards him in the beginning, Jean Finley eventually felt Crockett was not the man for her daughter. Crockett declared his intentions to marry Polly, regardless of whether the ceremony was allowed to take place in her parents' home or had to be performed elsewhere. He arranged for a justice of the peace and took out a marriage license on August 12, 1806. On August 16, he rode to Polly's house with family and friends, determined to ride off with Polly to be married elsewhere. Polly's father pleaded with Crockett to have the wedding in the Finley home. Crockett agreed only after Jean apologized for her past treatment of him.  The newlyweds settled on land near Polly's parents, and their first child, John Wesley Crockett, who became a United States Congressman, was born July 10, 1807. Their second child, William Finley Crockett, was born November 25, 1808. In October 1811, the family relocated to Lincoln County. Their third child Margaret Finley (Polly) Crockett was born on November 25, 1812. The Crocketts then moved to Franklin County in 1813. He named the new home on Beans Creek "Kentuck".  His wife died in March 1815, and Crockett asked his brother John and his sister-in-law to move in with him to help care for the children. That same year, he married the widow Elizabeth Patton, who had a daughter, Margaret Ann, and a son, George. David and Elizabeth's son, Robert Patton, was born September 16, 1816. Daughter Rebecca Elvira was born December 25, 1818. Daughter Matilda was born August 2, 1821.
