Valko Family History
Valko Name Meaning
Czech and Slovak: pet form of the personal name Valentin (see Valentine). Hungarian (Valkó): from a pet form of the personal name Valér, from Latin Valerius (see Valerio). Hungarian: probably also a habitational name from any of various places called Valkó or a regional name from a former county so named, although in this case the correct form of the surname would be with the suffix -i (i.e. Valkói or Valkai).
