Anna Miller Costantini

Anna Miller Costantini was an American novelist born in 1880. Reliable catalog and public-domain book sources consistently identify her by that birth year, and surviving records of her work show that she published fiction in the early 1900s.

She is best known for Ragna, published in 1910, a novel that follows a young woman from a rugged childhood in Norway into a more polished world in Paris. Modern library and public-domain listings also connect her with The Gulf Between, suggesting a small but notable body of fiction rather than a long, heavily documented literary career.

Very little widely available biographical detail appears to survive online beyond her name, birth year, and books. That scarcity gives her work an archival kind of interest today: she is one of those authors remembered mainly through the novels themselves and the libraries that have kept them in circulation.
