I suggest they could be from
Rybarzowice
http://en.wikipedia.org/wiki/Rybarzowice,_Silesian_Voivodesh...and Buczkowice
http://en.wikipedia.org/wiki/BuczkowiceTheir Polish families could be Maślanka
http://www.moikrewni.pl/mapa/kompletny/ma%25C5%259Blanka.htm...and Raczek
http://www.moikrewni.pl/mapa/kompletny/raczek.htmlIt is only 2 km from Rybarzowice to Buczkowice.
Some Maślanka and Raczek still live there (phone book).
And one more thing, Polish sound "rz" Hungarian ear hears "zs", and could have been in Hungarian written something like "Ribazsowicze". Buczkowice could looked for instance "Bucskowicze".
