Game Of Thrones Theory: Jon Snow has a Twin Sibling and its not Young Griff

One specific theory is about a twin sibling of Jon Snow born at the same time. That sibling is Meera Reed sister of Jojen Reed and daughter to Howland Reed who saved Ned Stark's life in a battle at the tower of joy.

Howland Reed was there when Ned Stark went to save Lyanna. Ned took Jon and Howland took Meera. She is the same exact age as Jon in the books and has the same curly black hair and light skin. Her features are very similar to Jon's. In the books both of them are 22. Jon is like 13 at the beginning of the first book and so is Meera.
