One of the problems you are going to run into in researching Hungarian family history is the fact that Upper Hungary was given away to Czechoslovakia at the end of the First World War. Once the Slovaks became in the majority in the Country, one of their first acts was to change the names of all the towns and villages to Slovak names. The town has continued to thrive as a border crossing. This can present you with a bit of a problem if you are unaware of the old and new names, this can be complicated further by the fact that German immigrants into certain areas gave a third name to some of the towns and villages, that frequently does not resemble the Slovakian name at all. Reading through this you will discover that the capital of Slovakia, once upon a time the capital of Hungary when the Turks occupied the middle of the country, is known today as Bratislava, was known to the Hungarians as Pozsony and to the Germans as Pressburg.
