Hey, I get that this is a Longshot and I probably won't get any help, but I'm trying to make a family tree because geneology is cool and I'm into that shit.

But anyways, my trail has gone cold on my great grandmother (technically a step great grandmother but no one else in my family knew a different woman as a mom/grandma). She was born in Vladivostok in 1913 and left the Soviet Union, I have been able to find two documents saying she was stateless and fled to the Philippines via China and then the USA via the Philippines, I can not find anything else about her, but I'd like to find out about her parents, does anyone know any good recourses for old Russian records or is this a lost cause?
