Ermine Street
It was named after a tribe called the Earningas, who inhabited a district later known as Armingford Hundred, around Arrington, Cambridgeshire and Royston, Hertfordshire. The Anglo-Saxon name was 'Earninga Straete' (1012). 'Armingford', 'Arrington' and 'Ermine Street' are names that share the same Anglo-Saxon origin.
It is also known as the Old North Road from London to where it joins the A1 Great North Road near Godmanchester.
