[Antoninus]

The postulated group,who he refers to as "Albans",are supposed to have established outposts across the southern Arctic,and as far south as the present day Maritime Provinces.

Maybe the Irish. Isn't there a legend of St. Brendan sailing off to the West?

There's a legend to that effect somewhere,although I can't cite a source for it(the St. Brendan legend). Regarding linguistic affiliations between European languages and Native American languages,try looking at a book by Barry Fell,called America,B.C. Fell makes a reasonably good claim for some of the northeastern tribe's words-place names in particular-to have Celtic roots.

In fact,thinking about it,the Albans that Mowatt refers to would-again,assuming they existed-have probably spoke a Celtic based language,since Mowatt places their origin in Gaul.
