I wonder what the original gods of the First Men were... Did it say in the books and I've missed it? They took up the Old Gods of the Children, but what did they believe previously?
We have looked at this before and as much as we would like to know there is not anything solid only a few things to consider. Black Crow already mentioned the the fire elements in the Night's Watch vow that has to make us wonder. I've tried looking at house sigils of First Men with fire symbolism but IIRC it was a mixed bag, maybe some in the Iron Islands but I'm not sure now.
Next you can look at the Iron Islands because they are First Men and supposedly the Andals adopted their beliefs instead of the other way around. Then you could wonder about all these gods in Westeros, which could come from many other origins too but who knows. The Drowned God, the Storm God, the Cold God, the Sea God, the Goddess of the Wind, and more I can't remember now but they have some in Essos as well, you also have stories of mortals marrying the gods.
One last thing too, that does not really help at all, is it seems like the First Men ( Starks and Greyjoys ) are described with dark or black eyes and so are the Dothraki and I remember an interesting thread from Bran Vras that discovered it might be possible the First Men come from a horse culture. So in the end no we do not know what the religion of the First Men was but not from lack of trying. /smile.png' class='bbc_emoticon' alt=':)' />
