If you find your family, I am willing to go with you to meet them and interpret depending on schedules etc. Be careful as there are crooks who will send false information. I made sure I had the correct family for him by asking questions from info he provided to me. I asked them to show him old letters from his ancestors sent to Cz. I can access church records also.
All research is for Czech Republic only.
If no information available I will tell you. Some towns in Cz no longer have the same name. Many streets have had names changed. I have access to the changes to the extent they are available. You must remember that during German and Communist occupation that many records were destroyed.
