>>> Is there a map available online that is recommended to locate towns? Are several maps needed due to the changes that took place...to borders, town names, counties, areas...over the years? What would you suggest? <<<
To locate places in Europe, especially if you are not sure of the proper spelling of the place name, the best reference is found at http://www.jewishgen.org/ShtetlSeeker/loctown.htm
ShtetlSeeker will take you there via Mapquest, Multimap or Google.
1910 HUNGARIAN MAP
The old Hungarian map can be found at: http://lazarus.elte.hu/hun/maps/1910/
SAVE the map on YOUR computer. OPEN the map in any graphics program. CUT and PRINT the relevant section of the map. Otherwise, you just get a corner. This map uses the Hungarian village names that you will likely find in church records.
