You are very fortunate to have been able to go to the Czech Republic and see the place where your ancestors have come from. I will make that same trip my self some day.
From the early information I have received from the researcher I hired in the Czech Republic my ancestors actually lived in the village of Mnich which is southeast of Kardosova Recice itself.
I did find out that my female immigrant ancestors grandmother was Mariana Zachova (Zach) from Mnich.
I hope this helps in someway.
