When President Trump visited Scotland this week, the first official gift he received was a 1921 census record from the Isle of Lewis in the Outer Hebrides, with details of his Scottish-born mother, Mary Anne, then 9 years old. Scotland’s first minister, John Swinney, also presented a document dating from 1853 that registered the marriage of Mr. Trump’s maternal great-grandparents. And there was a third gift, too: a historical map of Lewis. In exchange, Mr. Trump gave Mr. Swinney something rather less personal: an American bald-eagle figurine. Here’s a selection of noteworthy offerings exchanged when American and British leaders have met — and a couple of examples from elsewhere in Europe, too.
