Should all Czech people's last name end with -cova? Like Petra Nemcova, Karolina Kurkova, Daniela Pestova?

Question

EDIT: ends with -ova

Answer 1

How about Martina Navratilova?

Answer 2

no, not all czech people's last name end with - ová

only _FEMALE's_ last names end with - ova.... however not  all female last name end with - ova ... there are other endings for females...

e.g.

male (Svoboda) - female (Svobodova)

male (Čenský) - female (Čenská)

I hope this answered your question.
