Helen A. Manville (née, Wood; pen name Nellie A. Mann; August 3, 1839 – 1912) was an American poet and litterateur of the long nineteenth century.

[1] Under the pen name of "Nellie A. Mann", she contributed largely for leading periodicals east and west, and obtained a national reputation as a writer of acceptable verse.

[3] She inherited literary talent from her mother, several members of whose family won local celebrity, and who were connected with the Carys, from whom Alice and Phebe were descended, and also the house of Douglas, whose distinguished representative was Stephen.

Renouncing her pen name, she assumed her own, and in 1875, published a collection of her poems entitled, Heart Echoes,[6] which contained a small portion of her verse, for she had been a voluminous writer.

[5] Her spirituality was pronounced, and an abiding faith in a supreme wisdom, whose dictations proceed from infinite love, carried many a message of comfort to sorrowing hearts, and inspired strangers to become her grateful friends.
