Passage: Johnny Cash was born on February 26, 1932, in Kingsland, Arkansas, to Carrie Cloveree (née Rivers) and Ray Cash. He was the fourth of seven children, who were in birth order: Roy, Margaret Louise, Jack, J. R., Reba, Joanne, and Tommy (who also became a successful country artist). He was primarily of English and Scottish descent. As an adult he traced his surname to 11th-century Fife, after meeting with the then-laird of Falkland, Major Michael Crichton-Stuart. Cash Loch and other locations in Fife bear the name of his family.At birth, Cash was named J. R. Cash. When he enlisted in the United States Air Force, he was not permitted to use initials as a first name, so he changed it to John R. Cash. In 1955, when signing with Sun Records, he started using the name Johnny Cash.In March 1935, when Cash was three years old, the family settled in Dyess, Arkansas, a New Deal colony established to give poor families the opportunity to work land that they may later own. From the age of five, Cash worked in cotton fields with his family, singing with them as they worked. The Cash farm in Dyess experienced a flood, which led Cash later to write the song "Five Feet High and Rising". His family's economic and personal struggles during the Great Depression inspired many of his songs, especially those about other people facing similar difficulties. Consequently, Cash had sympathy for the poor and working class throughout his life.
