Elner is of Scandinavian origin, derived from the Old Norse 'Æln', which means 'elf' or 'fairy'. It's a unique and unusual name that was brought to prominence in North America by writer Ethel Wilson, who used it for one of her characters in her 1955 novel 'The Pumpkin-Eater'. The name Elner has since gained popularity as a distinct choice for parents seeking an uncommon yet charming moniker.
"The name Elner experienced fluctuating popularity between 1904 and 1950, peaking in 1920 with 20 births, but seeing a significant decline by the late 1940s."
