Of the five places called Długołęka in Volume XV of the Słownik Geograficzny Królestwa Polskiego i Innych Krajów Słowiańskich (Geographical Dictionary of the Kingdom of Poland and other Slavonic Countries), the third and fourth are located near Białystok. The third entry in volume XV, located 23 versts (about 23 km) from Białystok, is found on the Third Military Mapping Survey of Austria-Hungary. I could not find the fourth entry, located 43 versts (about 43 km) from Białystok, on those same maps. The entry for Długołęka in Volume XV of the Słownik Geograficzny was translated in a previous post.
