Jobete, as in the Motown publishing company, is Jobete because it was named after Berry Gordy's children Hazel Joy, Berry & Terry.
However, perhaps someone may have made a mistake when writting / printing some labels thinking should be Jobette as in the diminuative form of a word e.g. kitchenette, masonette or the feminine form of a name e.g. Paulette Reaves, Jeanette Harper?
