1869–1952
Known for warm, humorous domestic fiction, this British novelist built a loyal readership with cheerful stories about marriage, family life, and everyday misunderstandings. Several of her books remained well enough known to be adapted for the screen in the 1920s.

by Mabel Barnes-Grundy
Mabel Barnes-Grundy was a British novelist born in 1869 and died in 1952. Sources available here identify her as an early-20th-century writer, and reference works describe her fiction as notably cheerful, with a strong focus on romance and domestic comedy.
Her work includes novels such as Dimbie and I—and Amelia and The Mating of Marcus. Public-domain library records show that her books continued to circulate widely, and film references note that The Mating of Marcus was adapted as a silent film in 1924.
While detailed biographical material is limited in the sources I could confirm, the overall picture is clear: she wrote popular, light-hearted fiction centered on relationships and social life, and she remains of interest today through digitized editions of her novels.
