Vanninen Genealogy and Vanninen Family History Information

My mother told me that her mother, Aleksandra (Sanni) Soikkonen, born in Kitelä 1909, worked by a family Vanninen in (or around) Viborg (Viipuri) from when she was only eight years old. She took care of children in that Vanninen family sometimes, and sometimes went to school in Kitelä. I guess that family Vanninen in Viborg had relatives in Kitelä(?).
