You may find a number of noble families owned land in Gonc-Ruska over time including Kornis de Goncz-Ruszka.
My personal research has taken me to the records for this town as has the 1828 census.
Heraldry, Arms, Coat of Arms, Family Crest; what do these terms refer to? The Crest itself is the image within a fancy framework. The framework is the Coat of Arms. There is an entire language of design, color, and symbols to them that varies by country and ethnic identity which is a study in itself.
Nobles used designs like these on flags, signet rings, seals, wall hangings, and so on. Today we think if them as logos for brands.
