Etherine is a distinctive and lesser-known given name of French origin, derived from the Greek word "aither" meaning 'pure' or 'upper air'. This name gained prominence during the Middle Ages in France, often bestowed upon young girls as an expression of purity and lightness. It is a unique choice for parents seeking a rare yet meaningful name for their daughter.
"Etherine was a relatively uncommon name during this period, with fewer than ten births recorded each year from 1915 to 1953. The name's popularity seemed to peak in the late 1920s and early 1940s, with years like 1923 and 1946 seeing six births each."
