Caleb Ginyard Jr. was born 15 January 1910

Caleb Nathaniel Ginyard Jr. (January 15, 1910 – August 11, 1978), known as Junior Caleb "J. C." Ginyard, was an American gospel and doo-wop singer and songwriter who performed with various vocal groups between the 1930s and 1970s, including the Royal Harmony Singers, the Jubalaires and the Du Droppers. 

The Jubalaires

Caleb Nathaniel Ginyard, Junior was born in St. Matthews, South Carolina. Since he was Caleb Nathaniel, Junior, people took to calling him "Junior Caleb", and that's where the "J.C." came from. He sang in his church as a youth before becoming a professional singer as a tenor (later baritone). He started his singing career as one of the founders of the Royal Harmony Singers in Jacksonville, Florida, in 1936. They moved to Philadelphia in 1941. The group worked on the Arthur Godfrey radio show in New York and later renamed their group as the Jubalaires, appearing in several movies and shorts. In 1947 Ginyard left the Jubalaires to form a new group, the Dixieaires, who remained together with a varying membership until the mid-1950s.

In 1952, Ginyard also formed a secular vocal group the Du Droppers. The original members were Ginyard  on lead, brothers Willie Ray and Harvey Ray on tenor and baritone, respectively, and Eddie Hashow on bass (who was soon replaced by Bob Kornegay).They would get together in the basement of his apartment house at 149th Street and 7th Avenue in Harlem. There was a piano there and the new group practiced until they felt they were ready to start a professional career. With the 15 years of experience that Ginyard brought to the group, they quickly attracted some attention. 

                                   

They began as a gospel group each member had been in previous gospel groups (including the Royal Harmony Singers, the Dixie-Aires, the Jubilaires, and the Southwest Jubilee Group). The Du Droppers began performing R&B vocal-group songs and soon auditioned for record producer Bobby Robinson and DJ Joel Turnero, both owners of the Harlem-based label and record shop Red Robin. Their first record, "Can't Do Sixty No More," released by the group in December 1952, was an "answer" record to the massively popular Dominoes hit, "Sixty Minute Man." It earned the group instant popularity and airplay, but Red Robin let the Du Droppers slip through their fingers; soon the group was recording for RCA Victor, one of the major labels looking to break out in the fast growing field of R&B.

In mid-March of 1953, their next single, "I Wanna Know," made a huge impact and climbed to number three. In June 1953, the Du Droppers released the follow-up to their RCA smash, and "I Found Out (What You Do When You Go Round There)" climbed to number three on the pop charts. Both hit records  were either written or co-written by Ginyard. Soon they were embarking on a late-summer tour of one-nighters through the South with the Joe Morris Blues Cavalcade. Subsequent singles, however, failed to generate much new interest in the group. In November, RCA paired the group with pop music singer Sunny Gale for a (now highly collectable) single, "Mama's Gone Goodbye." 

In 1954, the Du Droppers began recording for a new RCA subsidiary, Groove Records, which was meant to be strictly for R&B acts signed to the major label. Unfortunately, they failed to improve upon their track record and subsequent Groove singles saw them slipping from the charts. In early 1955, Groove attempted to persuade Ravens' vocalist Joe Van Loan to join the group and help shake things up, but he was already under a personal service contract with Herald Records; while this was being sorted out, Charlie Hughes was brought in to sing lead on recordings only, though he wasn't allowed to perform with the group. In August, the label issued one last single, but soon thereafter, Junior Ginyard retreated back to gospel music, joining the Golden Gate Quartet, so the others decided to call it a day. 

Ginyard was with the Golden Gate Quartet from 1955 until 1971, by which time they'd all relocated to Europe. Those years with the Gates sparked the most brilliant repertoire of Caleb's career. His addition to the group inspired the hallmark years of the Golden Gate Quartet as well. Due to failing health  he moved to Basel in Switzerland but continued to and perform as a soloist until his death on August 11, 1978 at the age of 68. 

He was married to Janie Elnora, née Flowers in USA having five children and also to Gunilla in Sweden having two children. A Father and Son Autobiography of A Spiritual Music Genius was published by Ginyard's son Caleb Ginyard, III .
