Cameliard in Scotland?
(Source: Poetical Works of Alfred Tennyson, Volume 4)
I've noticed a minor recurring idea in some (modern) works, that Cameliard - the home kingdom of Guinevere and Leodegrance - is reckoned to be located in Scotland.
This is interesting to me because depending where in "Scotland" Cameliard is located, it may potentially square with the few geographical details we know of about Cameliard, mostly from the French Vulgate Cycle that introduced it. And, in turn, may lead to some very hilarious implications.
What I'm curious about though is from where did this idea came about and what's the earliest source this concept was proposed. Is Tennyson the earliest this comes up? Or did this Scotland theory originate elsewhere?
*On a different note, other sources, like Wikipedia, claim Cameliard had to be in Cornwall or associated with Cornwall in some way. This is rather incredibly unlikely as the location is already rather "crowded" within Arthurian canon, what with the Tristan story, Gorlois, its close proximity to Brittany and the Kingdom of Dumnonia. Moreover, the claim seems to be derived from the association Guinevere has with Cador of Cornwall who, in Geoffrey's chronicle, was merely her tutor and guardian. More believable are the Oral sources for Guinevere's home, which point to an area in Wales, but that's another topic for discussion.
