In 1927, she and A. P. began performing as the Carter Family, perhaps the first commercial rural country music group. They were joined by her cousin, Maybelle, who was married to A. P.'s brother, Ezra Carter. Later, Sara married Coy Bayes, A. P.'s first cousin, and moved to California in 1943, and the original group disbanded. In the late 1940s, Maybelle began performing with her daughters Helen, June, and Anita as The Carter Sisters and Mother Maybelle (the act was renamed The Carter Family during the 1960s).
