I have a question about the 1921 Czechoslovakian census ( https://library.hungaricana.hu/hu/collection/KarpataljaiNepszamlalas1921/ ). Part of my family lived in Beregrosztoka, in Huszt County, Zakarpattia Oblast. The village was also known as Gazlo and Roztoka, and nowadays as Velyka Roztoka. I cannot find this village in the census, even though many surrounding villages do appear in it and are digitized. Does anybody know how to find Beregrosztoka in this 1921 census?
Thank you!
