The Scandinavian Secret Hidden Inside America's DNA Database

In a quiet Utah valley, the names in a nineteenth-century ledger don't read like the American frontier at all. They read like a Copenhagen phone book. This is the story of a migration almost no one talks about, and how it ended up shaping one of the most important tools in modern genetics. A small mountain town, a religious mission, a transatlantic crossing, and a laboratory in Paris all turn out to be connected in a way that even geneticists found surprising. By the end, you'll never look at a DNA ancestry result the same way again.
