Hello Statia,

No my last name is not Cermak, but in my maternal line I have a Veronika Cermak who was born about 1732 in Klaster, Waldstejn Estate. The mtDNA would be the same for her as it is for me.

That's a really simple explanation. There's a lot of information about mtDNA and how to trace ancestors on familytreedna.com
