How to write to possible distant relatives in the "old country" ?
I suggest a letter in Czech (if at all possible) with family information, do include your e-mail address and a photo of your ancestor.
A spelling ZAK shows up in Kardasova Recice's phone book. You might want to send a letter to them and to a NOHAVA that too list in KR.
