Some of the proposed ancestor are;
- Giants were claimed by Osha because of his great size.
- Ser Duncan the Tall because of his height and because George R. R. Martin stated that his descendant would be in the book. There is also the vision of Bran's in the cave of the three-eyed crow of a knight as tall as Hodor kissing a young woman at Winterfell. The woman is thought to be Nan and the knight to be Ser Duncan the Tall, when he and Egg visited Winterfell in The She-Wolves of Winterfell.
- A member of House Frey because his real name is Walder and being slow witted runs in House Frey, i.e.Jinglebell.
Origin of 'Hodor'; Hodor may in fact be the name of the Great Other. Melisandre says his name must not be spoken, so few people, if anyone, would recognize the name if they heard it. Old Nan says that Hodor's name is really Walder, and that no one knows where he got 'Hodor' from. There is a fair amount of Norse Mythology (which GRRM may have been influenced by) suggesting the connection. For example; the Great Other is the god of the cold and dark, and in Norse Mythology, there is a god named Hod/Hodur/Hoder who is the god of all things cold and dark.
