Wikipedia is the first hit if you tried Googling...
"In the Greek mythology the name Protogenoi (pl.; Gr. ????????????????????, sing. Protogenos) means First Born or Primeval and are a group of deities who were born in the beginning of our universe.
The Protogenoi are the first entities or beings that come into existence. They form the very fabric of our universe and as such are immortal. The Pr??togenoi are a group of gods from which all the other gods descend. Although generally believed to be the first gods produced from Chaos, some sources mention a pair of deities who were the parents of these Pr??togenoi. These deites represent various elements of nature."
And then there is a list of names of the supposed 'Protogenoi'; from: http://en.wikipedia.org/wiki/Protogenoi
I'd love to discuss this further but I'm in the middle of homework. I'll come back!
