Decca, derived from the Italian word 'deca', meaning 'ten', is a unisex given name of Latin origin. It gained popularity as a given name in the latter half of the 20th century, often used as a shortened form of names like Decima or Decibel. The name Decca has been popularized by several notable figures, including Decca Records, one of the leading independent record labels founded in London in 1929. However, it is important to note that the use of this name as a given name predates the establishment of the record company.
The name Decca was given to five girls born in 1956.
