Almetta is of American origin, derived from the English word 'almeta', which translates to 'sweet'. This unique and historic name was popular during the late 19th to early 20th centuries in the United States but has since become quite rare. It is often associated with the Southern states during that period.
"Almetta saw its peak popularity between 1921 and 1926, with 17 and 15 births respectively during those years. However, it appears to have been quite uncommon overall, with fewer than 10 births in most years and a significant decline after the 1930s."
