What gods were least affected during the Greco-Roman divide? [hoo]

I seem to recall a few instances wherien the 7 mentioned that xyz God was not as affected with the divide as others, but I cannot pinpoint this for the life of me. Was it Nyx? Or some god that did not have a Roman counterpart.. No idea xx
As a bonus, which God not interacted with in HOO do you think would also be affected minutely?
