NIKOLAJ ZMOROVICH
The furthest of known ancestors - Nikolaj Zmorovich, father of my grandmother's Larisa grandmother. On this photo he is - presumably - with his son, Kapiton and his wife. (?). Below you can see another photo, with - I believe - the same Kapiton, but years later.
So, I think here is Kapiton with family. The young girl on the right - Olga Kapitonovna Zmorovich. I knew her in my young years. She was my grandmother's cousin.
Kapiton descendants live in Moscow (Dmitriy Smirnov) and in Paris (Inna Dmitrievna Vassilieva and her son, Vladimir Veksler)
