I asked earlier:
"Do these years have online databases and indexes that can be computerized
search? Or if I want to search census I have to read the original documents
of the Census of the Hungarian National Library? "
I'll fix a little my question:
I realized that censuses before 1830 are not available for searching
JewishGen. Are there other places that I can search on those years in
Hungary online? if not, how do I do that?
