An interesting discovery today on the internet! I found this publication, Családnevek enciklopédiája, written by Mihály Hajdú which contains approximately 1,230 of the most common surnames up to the 19th century. In addition to explaining the frequency of the surname, it also explains the surname's origin, meaning and spelling variations. Surnames of other common languages such as German, Slovak and Romanian is also provided.
You can find the publication here.
