A younger sister of Hidle Brown Barnum, Jr., she was a vocalist who graduated from Salinas High School in Salinas, California, in 1955, and a decade later joined the all-girl R&B group, The Apollas. They signed with Warner Brothers’ soul division, Loma Records, and released a series of singles that did little more than flirt with chart success. They broke up in 1968.
