You're right Jo, I wasn't clear.
The question came up asking if "{{Unsourced|England|Devon}}" was correct & I went looking to see if England Project said whether or not to include the country or just the county. Since I didn't find an answer, I asked here.
However, in the Google Group discussion you referred to (I think - I don't recall who the OG was), Aleš has since posted a reply to use just the lowest location, so {{Unsourced|Devon}} is correct, not {{Unsourced|England|Devon}}
