Earnestene, of Latin origin, is a unique and uncommon given name for females. It is derived from the Latin word 'earnestus,' meaning serious or solemn, combined with the feminine suffix '-ene.' This name was more prevalent in the United States during the late 19th to early 20th centuries but has since become quite rare.
"Earnestene was popular among parents for brief periods over several decades, peaking at nine births each in 1923 and 1928."
