N. S. (Nannette Snow) Emerson

N. S. Emerson, also listed as Nannette Snow Emerson, was an American writer born in 1840 and died in 1884. Library and public-domain book records connect her with works including The History of Dungeon Rock (1859), A Thanksgiving Story (1873), and Dungeon Rock; or, the Pirate's Cave, at Lynn.

Her best-known writing centers on Dungeon Rock in Lynn, Massachusetts, suggesting a strong interest in local history and legend. That mix of regional subject matter and accessible storytelling gives her work a distinct place among lesser-known nineteenth-century American authors.

Some records also identify her as Nancie Snow Emerson French, but the available sources are limited, so it is best to treat that detail with caution. I wasn't able to confirm a reliable portrait from the sources I checked.
