Dear Kim
My name is Peter Csallo (Csalló), and I'm from Hungary.
In 1500-1600 years a Czech valiant came to Zala county (south-west part of Hungary), and he found Csallo family. We live (me and our family) in Zala county too. This family name not so familiar in Hungary. I think less than 5000 people have this family name :)
If you have any questions, please ask me. My address is tade24@freemail.hu
Best regards,
