I don't know if its been said before but in the Trinity Series (Fiona McIntosh) there are mentions of places that sound like Dorne and the Vale. There's also a clan of people (I forget but I think they were cannibalistic) that resemble the wildlings. In the Trinity books there is a goddess named Lys and the name of the protagonist is Torkyn often shortened to Tor. There's a similarity in the names in Asoiaf and trinity. Another similarity is the way they portray the prostitution and brothels. They have a sort of Oldtown-like place as well. There's pirates and hangings and wizards and all that. I don't know if this helps but I'm just saying.
