Thanks to Marla Raucher Osborn who pointed out on Gesher Galicia’s Facebook page that the Austrian National Library recently posted scans of historical newspapers from Austria, including Galicia, to their web site. The site is in German, but I recommend loading it in Google Chrome, and using the automatic translation capabilities of Chrome to navigate the site. Unfortunately, besides being in German, much of the newspapers are printed in Gothic script. There is a relatively good search interface.

A search for Kańczuga currently finds 171 results:

Some of the results includes news from the town, some are casualty reports from WWI, and some I have no idea. It would certainly be welcome if someone with German skills, including the ability to read Gothic script, could take a look at the search results and see if they could determine which references to Kańczuga and the surrounding villages here are relevant.
