M. Harding (Minnie Harding) Kelly

Project Gutenberg identifies this author as Kelly, M. Harding (Minnie Harding) and currently lists The Secret of Oaklands under that name. The available public record in the sources I found is quite thin, so only a few details can be stated confidently.

From the text of The Secret of Oaklands, she was presented as M. Harding Kelly and also credited with other novels including Philip Campion's Will, Roy, and Tom Kenyan. The edition digitized by Project Gutenberg was published in London by R.T.S.–Lutterworth Press, which places her within the world of British popular and morally minded fiction for younger readers.

Because biographical information appears to be scarce online, it is safest to remember her through the books themselves: stories shaped by domestic drama, suspense, and character-tested decisions rather than flashy spectacle. That relative obscurity is part of the appeal for many modern listeners, giving her work the feel of a rediscovered classic.
