Hi Danny, normally I would agree that "Horst, Provinz Pommern, Preußen, Deutscher Bund" is good enough.
Unfortunately there were at least 2 different villages with the same name in Provinz Pommern. This one, now called Pęplino, was in Kreis Stolp.
There were more Horsts in Provinz Pommern, one in Kreis Pyritz and another in Kreis Regenwalde. In these examples it becomes important to identify the kreis as well.
One level I would leave out of Florian's answer is the Regierungsbezirk: Köslin
