> At least half of its residents could make that particular edit What proportion could/would actually cite a source for the edit, though? It's likely not that hard to find a source: the local library probably has some local-history books that explain the source of the name. But in my experience the proportion of people willing to open a book before making an edit is smallish. There are some local "edit-a-thons" trying to improve that, though. I've never been to one myself, but from what I can tell they tend to be organized at libraries or universities, and the organizers have already pulled out some relevant reference materials, so people can more easily start making cited improvements to articles about their local area.
