The people/tribe of Danú (a Celtic god)

The Children of The Forest remind me of the Tuatha Dé Dannan of Irish mythology. They were a magical race who ruled Ireland until the Celts arrived, fought a war against them and eventually agreed to a truce, before moving into caves and the underground and becoming forgotten except in the stories and legends.

Tolkien took warg from Norse mythology where vargr was a term for wolf.

Tully is a pretty common Irish surname. Originates from my home county of Galway. One of my best friends is a Tully. It means "flood" in Gaelic, which is interesting as the ASOIAF Tullys are based in the Riverlands. If I recall correctly, their coat of arms has 3 wolves heads on it and their motto is something to do with unity and strength, so a bit more Stark-ish than Tully-ish.

I think the English word "stark" is more relevant, meaning grim, harsh, blunt. No frills, no smoke and mirrors.

There's a slight similarity between King Roberts death and that of Diarmuid from Irish mythology. Legendary warrior Fionn MacCumhail is married to the High Kings daughter Grainne. She doesn't like him much and runs off with one of his warriors Diarmuid. Fionn and Diarmuid are eventually reconciled and Fionn arranges for them to go on a boar hunt. While on the hunt Diarmuid is gored by a giant boar, although he managed to kill it. Fionn has the power of healing and could heal Diarmuid by letting him drink water from his cupped hands, but after taking water from a stream he let it spill through his fingers and Diarmuid dies. Also, and this is very tenuous, Grainnes father Cormac MacAirt had 4 woves who accompanied him to battle, and who he could understand.
