To Mary's answer I add.
Suname with y in the end, for example Novy = male - Nova = female. Stary - Stara, Holy - Hola and s.o.
In old records are in German used "-in" in end: Novak - Novakin, Novy - Novin Holy - Holin.
In old records in Latin are often used "-iana" in end of female's surname: Novak - Novakiana, Novy - Noviana.
All the best.
