Born J. R. Cash in Kingsland, Arkansas, the third of seven children to Ray Cash (13 May 1897, Kingsland, Arkansas – 23 December 1985, Hendersonville, Tennessee) and Carrie Cloveree Rivers (13 March 1904, Rison, Arkansas – 11 March 1991, Hendersonville, Tennessee).
Cash learned upon researching his ancestry, that he was of Scottish royal descent. After the opportunity of meeting with former Falkland, Fife laird, Major Michael Crichton-Stuart, he traced the Cash family tree to 11th-century Fife, Scotland. Scotland's Cash Loch bears the name of his family. He had believed in his younger days that he was mainly Irish and partially Native American, including Cherokee and Choctaw. Though Cash learned he was not of Native American descent, his empathy and compassion for Native Americans was unabated. Such feelings were expressed in several of his songs, including "Apache Tears" and "The Ballad of Ira Hayes", and on his album, Bitter Tears: Ballads of the American Indian.
