There's two or three villages in Scotland that I know of. Honestly, I don't know that much of the language's history, just that we've spoken it for a long time. Also, spelling is a bit off at all times because it's not standardised, so there could be dozens of spellings for a single word. Also, it's not the same dialect, it's generally the same, yet some gaelic words crossed over in Scotland. Allucairn's dialect sounds much more like Gaelic than it does like Welsh, even though most words are the same.
