Hello, I'm looking WALZ (maybe WALTZ) families.

My grandma - MARIA WALTZ (WALZ) (b. 190x, d. 1974).
Before WWII her family lived in Ukraine (near Dnepropetrovsk city). I don't known names of her mother or father, sorry...
She married KUZMA CHAYUKOV.

They had two children- daughter Ludmila (my mother, 1936-2002) and son Alexander (my uncle, b. 193x).

Maybe someone knows WALZ (WALTZ) or Chayukov families from Ukraine (Dnepropetrovsk), please help...

Few days ago I found information about Piotr (Peter) WALZ (b. 1912) which was born from Shchorsk (~50km from Dnepropetrovsk). He was soldier at war and was killed in 1944. Maybe this man was from same family as my grandmother?

Thank you.

P.S. When my mother LUDMILA CHAYUKOVA was alive once time tell me name of village where they lived... she said that this place was about ~40km from Dnepropetrovsk. I was little boy I don't remember now exactly.... but it was german name (like Neuedorf, Neubach or smth..) not russian (not like Andreyewka, Golubewo or smth...)
