The Consular Section of the Embassy of Hungary in Washington DC, or the Hungarian authorities (e.g. the Ministry of Foreign Affairs or the Mayor's Offices) do not do genealogical research. 

Some information on the subject may be obtained (also in English) at the homepage of the National Archives of Hungary ( ).

You can find on the internet several companies doing genealogical research on the Hungarian site: and  or by typing in a search engine (Google, Yahoo, etc.) e.g. the key words: Hungary genealogy.
