::::::But what is the understanding of nationality on WP? Neither of your links prevent Scottish being used here. The WP:OPENPARA section on nationality says: “In most modern-day cases this will mean the country of which the person is a citizen, national or permanent resident, or if notable mainly for past events, the country where the person was a citizen, national or permanent resident when the person became notable.” So Scotland is a perfectly acceptable use, unless you contend that Scotland is not a country. If you are unsure what nationality to use, read the essay WP:UKNATIONALS, the purpose of which is to “aid the encyclopedia itself (by providing information, instructions, interpretations, or advice).” Nationality is defined as the sense of belonging to a particular nation. As you agree that Scotland is a nation, and John Brown is verifiably Scottish (i.e. a member of the Scottish nation) what can be gained by describing his nationality otherwise? You say: “Even if no Google-able sources ever describe him, however casually, as "British", that really doesn't mean that he wasn't, as a matter of simple definition.” Of course it doesn't, but two points. Firstly, as no sources describe his as British, that implies it is not notable; and secondly, (and once again, as the point has yet to be addressed), MOS:INFOBOX states its purpose is “to summarize key facts in the article in which it appears”. Nowhere in the article does it say he was British. The article says John Brown is Scottish. That is how it should appear in the infobox.
