Help Reunite a Mother with Her Russian Roots

I am starting this GoFundMe to help find my biological family. I was adopted from Russia back in 2004 when I was just 2 years old. I've known all my life that I was adopted and have always wanted to find my birth family. Recently, through the help of Ancestry.com, I found out I have a biological sister.

This has now prompted me to want to hire a private investigator to help me in my search of finding my other family members. I have tried contacting the adoption agency, and they have been far from helpful. I have also tried 23andMe and got nothing. The sister I found through Ancestry has not contacted me back.

I don't want to find my family just for me, though. I have two little girls, and so for them, I want to know what medical issues I should be aware of for their health. Any amount is appreciated!
