re: Question: Do you think GoT will delve into the history of White Walkers

This was at the back of my mind and I think I've finally tracked down at least some stuff on it:

At one point fairly on I remember that when trying to give some sort of info on the Others (White Walkers), GRRM mentioned something about entities from Irish folklore called the Sihe.

This is the best link I could find to that so far: Info on the White Walkers

Here's the quote:

“...The Others are not dead. They are a strange, beautiful...think, ok... the Sidhe made of ice, something like that... a different sort of life... inhuman, elegant, dangerous.” Game of Thrones: The Graphic Novel by GRRM

Interestingly when I googled Sihe it gave another name for them and said that the "usual spelling" was Sith. Aos Si (At least that was interesting to me since quite a few people were making comments/comparisons to Darth Maul in last week's White Walker/Night's King appearance).
