Gryniewicz (Гриневич)

I am searching for the daughter of Mikolaj & Natalia Gryniewicz of Dereweno, Belarus, who was the twin sister of my father, Wiktor Gryniewicz. Her married name may now be Wala, and she may live in Bzestskaja or Drewnaja with her husband or children.

Family Name: Gryniewicz, Гриневич (RU)
Name: Mikolaj & Natalia

Wiktor and his twin sister were born in 1925 and the children of Mikolaj and Natalia Gryniewicz.
