While searching Lycos for Ugocsa megye I came across this great atlas of old villages in Hungary.
VILLAGE FINDER - Hungarian Village Finder and Gazetteer for the Kingdom of Hungary. Includes more than 30,000 place names for villages, settlements, towns, and cities in the former Kingdom of Hungary. http://www.hungarianvillagefinder.com/http://www.hungarianvillagefinder.com/ [Translate]
You have to subscribe but I think every old town in Hungary must be listed here. Maybe it will help some of you trying to find your families places of origin.
