Origin: Greek

Meaning: Goddess of freshwater

Tethys is a feminine name of Greek origin and perhaps one of Greek mythology's most famous mothers. Conceiving a whopping six thousand children with her husband Oceanus, this goddess was also the goddess of freshwater. Her many, many children became the rulers of all the world's fresh bodies of water—rivers, streams, lakes, ponds, and even rain clouds! Whether baby becomes a parent or not, this name is a testament to perseverance in its purest essence.
