I’ve never seen this show, but find the name John Snow curiously similar to the name of the British Airborne Battalion commander at Arnhem, John Frost (portrayed by Anthony Hopkins in, “A Bridge Too Far”). The real Frost later retired as a general officer and served as an advisor to the film. Anybody familiar with GOT....are there any parallels between the characters other than the similarity of the names?
In the books out of wedlock children of the noblemen from the north were given the last name Snow. This identified them as illegitimate and would not be in line to inherent any property or title.
Ramsey’s last name is along Snow. He is the illegitimate child of Roose Bolton. Jon is the illegitimate child of Eddard Stark.
