чухонец

Pejorative name for Finns (female form чухонка). Finland can be called Чухня. Initially this was the name of a Finno-Ugrian tribe living in the vicinity of St-Petersburg and was then used to for Estonians before getting the current meaning.

На Сахалине попадаются избы всякого рода, смотря по тому, кто строил — сибиряк, хохол или чухонец.

On Sakhalin you can find all type of houses, depending on who build them: Siberian, Ukrainian or Finn.

(Антон Чехов, Остров Сахалин, 1890)
