Hello Beth,
Here is a list of houseplants that you could consider for growing in partial or very shaded areas:
Aglaonema
Aspidistra
Asplenium
Fittonia
Helxine
Philodendron
Sansevieria
Scindapsus
If you are to grow these in very shaded areas, you would be best to choose plain green varieties because variegated examples will need some light to maintain the variegation. As with most houseplants, avoid draughts, make sure the rooms are warm enough and most importantly of all try and maintain a decent air humidity by misting regularly or standing pots on trays of damp pebbles.
Hope I have been of some help,
