Hello, thank you for reply. I know that in Odessa there was many germans and possibly with Waltz (Walz) surname too. I think that in these times peoples don't went far from their hometown.

From my last post I have some information about my grandma. Her full name was Magdalena Waltz (or Walz) and one man told me that village where our ancestors live was near Sinelnikovo (~30km to East from Dnepropetrovsk). He told me that my grandma had two sisters and in WWII when they all were deported to Germany my grandma's sisters stayed in Germany after WWII.

I know that her (Magdalena's) husband was Kuzma Chayukov (1909-1952, died in Soviet concentration camp in Abez, Vorkuta). Him father was Ostah by name.

I think many my ancestors and relatives died in Holodomor or was killed by soviets NKVD :(
