Related to the book series A Song of Ice and Fire:
I forgot the assumed name of Jon Snows mother that was told to Arya Stark by a lord (forgot his name - first name Edrik I think), in the third book, A Storm of Swords. It was told to her when she was hold captive by the brotherhood, before the hound took her.
I think the first name was Wylla or something similar, although I may have remembered the name from when his father Eddard Stark said it in the first book, A Game of Thrones. Please correct and remind me of the real "assumed" name of Jon Snow's mother. Full name is required.
(keep in mind that I'm on the last written book of this series, no spoilers please)
