Jameca is of African origin, derived from the Fulani tribe's word 'Yamica', meaning 'may Allah protect'. It is often associated with Jamaican heritage due to its similarity in sound to Jamaica, but it predates the island's name. The name gained prominence in the United States during the mid-20th century, possibly due to immigration patterns.
"Jameca experienced peak popularity between 1978 and 1982, with a high of 17 births in 1982. However, its usage has since declined, with only 5 births recorded in 1996."
