The Csato surname is common in the Szekely Land (Terra Siculorum). Csatoszeg (nou Catatuia is Romanian) is a village, about 20 km far from Csikszereda. Almost in every village is a Csato, and I'm quite sure that they are in Csatoszeg too. In the late December I'll be in that area, I'll ask about the Csato family.
Please write me a note later not to forget is.
Sorry for my bad English.
