It is important, those documents are written in Hungarian, because I can be sure by the correct spelling only by this.
Otherwise I found a Susán in Mátraszele and called her, but she said, they are from Bárna (you can find it not far of Mátraszele). In Bárna near the all of familes have name Susán.............
In Mátraterenye I did not find any Susán, who would be in the phonebook.
Now I go home. Have a nice day!
