National Geographic: Was Gueneviere a Pictish Princess?

The new King Arthur film has National Geographic wading into the debate about the historical King Arthur and Camelot.

Glasgow historian Hugh McArthur believes Arthur's roots were near the Scottish border and that Gueneviere was a Pictish noble.

"There's a large number of place-names in the region which can be linked to Arthur," said McArthur. "At Dumbarton itself there's Arthur's Castle, and just to the west of Loch Lomond, there's a mountain called Ben Arthur, which includes a site known as Arthur's Seat."
