Does anybody have any clue where the name "Lois Fern" comes from?

I don’t expect anybody to know this, but it’s a Hail Mary.

In genealogical research you’ll see certain names become strangely popular: Paralee/Cumirah/Adelaide/Louisiana for example were all popular in the antebellum south, Viola/Lorena*/Florence/Mayvis/Edna Earl** all exploded in popularity, both north and south, immediately after the war.

But recently I’ve started seeing the woman’s double name “Lois Fern” in an increasing number of records. If it were just one or two then I would think it was coincidence, but in the 1930 census there are actually hundreds of women who had “Lois Fern” as their given names.

Does anybody have any idea why? I’ve wondered if it was a character from a late 19th century novel or song. I’ve googled and wiki’d to find out if there was a play/book/song but haven’t found anything.

Not a matter of earth shaking importance obviously, but just curious.

*The name of an extremely popular song in the war, which is probably not coincidental
**The name Edna Earl’s popularity was due to largely to its use as the name of the heroine of a book by a forgotten but once extremely popular author named Augusta Evans Wilson.
