Hi Denise,
I'm not sure what your post has to do with Hungarian nobility/royalty.. but if you want birth records for your family, you should go to your local FHC (Family History Center) and order the microfilmed records for the Lelesz church records. There are definitely Roman Catholic and Greek Catholic records available on microfilm for this town. Birth certificates didn't exist in Hungary until the beginning of civil registration records kept by the town in October 1895. Anything prior to October 1895 will have to be found in church records.
