Cornelia L. (Cornelia Louisa) Tuthill

Cornelia Louisa Tuthill was an American author whose published works date from the mid-1800s. Library and archive records identify her as the author of books including When Are We Happiest?; or, The Little Camerons (1848), Consecrated Talents (1852), Belle; or, The Promised Blessing, Herbert Atherton, and Our Little Comfort (1870).

Her books were largely written for children and family reading, often with a strongly Christian tone. Several were issued by religious publishers, especially the General Protestant Episcopal Sunday School Union and Church Book Society, which suggests that moral and devotional instruction was an important part of her work.

Cornelia L. Tuthill is also listed with Louisa Caroline Tuthill on My Little Geography (1847), indicating some form of collaboration or shared authorship. Clear biographical details beyond her dates are hard to confirm from the sources found, so her surviving reputation rests mainly on the books themselves and their place in 19th-century American juvenile literature.
