Since Balogh and Balog are very common surnames in Hungary, it is considered to be of Hungarian origin, deriving from balra 'left' + kéz 'hand' > balkezes 'left-handed' > balog, which is not very convincing. A serious researcher must respect the fact that in the Pannonian Plain lived Slovenes before the Hungarian occupation in the 10th century. Many words and names in the present Hungary reveal the typical Slovene origin (Budapest, Pecs, Revesz, macska,...), not Slovak or Croatian. The domestic people, with their names, language and habits lived lives on until their language was covered by the Magyar language, century by century. That development reaches 38% of the population in the Magyar-Orszag by the middle of the 19th century.See [Baloh]
