Is jahn a common german name?

As far as I'm aware the surname "Jahn" is quite common in Northern Germany, and most liguists take it to be a short form of the first name "Johann" (=John) which used to be very common, the name also exists as a surname in the long form.


That it has got anything to do with slavonic people is news to me.


N.b. : not every information on the internet is correct.
