10The Youngest Lord Commander Ever Was Only 10 Years Old
Jon Snow may know nothing, but it's safe to know that he probably knows more than a child. Before the Targaryens came to Westeros, the Starks were King in the North. One of their kin, Osric Stark, was chosen to be the Lord Commander of the Knight's Watch at a
mere 10 years old. He went on to hold that title for another 60 years. Why was he chosen so young? We're not really sure; it might be due to his family name or some unknown accomplishment. Regardless, Jon Snow was 16 when he was made Lord Commander, so at least there's some precedent for having a younger Lord Commander.
