In The Wheel of Time Companion, there are entries for both names. The first is referenced as being found in Andor, while the second is referenced as being found in the Waterwood of the Two Rivers and is probably a local name.
In the books themselves, Elayne Trakand makes the only reference in an analogy when she tries to unpick an unravelling Gateway:
To her eye the gateway resembled some monstrous, distorted hundred-heads on the bottom of a pond, surrounded by flailing tendrils, every one thickly haired with threads of the Power that grew and writhed and vanished only to be replaced by new.
Parallels
The name may be a reference to the Hecatoncheires, or "hundred-handed ones", of Greek mythology who each had fifty heads and a hundred arms, although they are quite different in form and size.
