From the experts:
This lively and appealing name originated as a short form of Cornelia, but is well able to stand on its own. Nelia is also often in the Hispanic culture, where it can be a short form of Manuela. It did have some American usage in the late nineteenth century, and with Cornelia having a comeback, Nelia could follow.
