Karpov in Yumatovka

[LaraBeth]

I am trying to find out anything I can about my Mother's family who lived in Yumatovka near Belgorod before WWII. (They fled then.) My Grandfather's name was Severian Alexandrovich Karpov, and my Grandmother was Olga Savinko (Karpov). Olga's parents were Alexander Savinko and Aghafia Kuzina (Savinko). I only know that my Grandfather's father was Alexander Karpov and his wife was named Maria... I have this information along with the names of my Great Aunts and Uncles, but no idea how to go about finding my relatives still in Russia! Does anybody know of a way to research this before I take my mother back to her childhood home (for the first time in 50+ years)?!

Thank you all, in advance
