For starters, JewishGen's Hungary Database has over 1.7 million records to peruse.  Currently, we are transcribing Budapest and Pest-Pilis-Solt Jewish Census records covering the years 1781 to 1846.  So far, we have 10,000 records transcribed, and hope to have the project completed by the end of  September 2020.  These records came from the Hungarian National Archives in Budapest.
