The story
Jensen is Denmark's most common surname, son of Jens, and Jens is John, which makes this the third name in these batches, after Jax and Zane's cousin story, to trace back to the same ancient well of Johns, this time through Copenhagen. The American record idled for a century, under 470 a decade into the 1980s, then climbed: about 2,000 in the 1990s, 2,200, then 8,400 in the 2010s, nearly four times over, the seasons a demon-hunting elder brother with this surname anchored television's longest-running fantasy drama; decade buckets point, they do not convict. It stands at 7,100 so far this decade. In our records it goes to boys about 17,300 to 2,900, with a real girls' share this decade of about 410. A patronymic that crossed an ocean and became a first name: Jens would be pleased, whoever he was.
