Note 91 — HISTORY OF CARNARVONSHIRE. (continued 2)
Reading edition
Carnarvon, does not owe its name to Edward I. as is generally supposed; for Giraldus Cambrensis mentions it in his memorable journey with the Archbishop, in 1188; and Llewelyn the Great dates from it a Charter, in the year 1221: probably the Caernarvon of those times was the ancient Segontium; whose name the Welch had changed to Caer-ar-Fon.
