We usually think of place-names as a modern invention, but in fact Arizona ranked on the US Top 1000 from its inception in 1880 until 1911, when it vanished below the surface. It peaked at Number 510 in 1882, before Arizona became a state. One notorious vintage bearer: criminal "Ma" Barker, born Arizona Clark.

This US state name has been rising slowly but steadily for girls over the last 30 years, but à la Dakota, it could easily be a male name too.
