My father, George Mescherski, with whom I was not close for many years as my parents divorced when I was a child, passed away in 2007 and left some unanswered questions about his roots.
All I know is that he was born in Istanbul in 1927 and left me the below ring:
Does anyone know where I can find additional information about my family?
Your father left you the ring with Princes Meshchersky's coat-of-arms and family motto "Strength is in Faith".
In Russian Internet one can find a lof of info on Princes Meshchersky.
In Russian Wikipedia, including picture of the coat-of-arms:http://ru.wikipedia.org/wiki/%D0%9C%D0%B5%D1%89%D0%B5%D1%80%D1%81%D0%BA%D0%B8%D0%B5
English Wikipedia (without c-o-a):http://en.wikipedia.org/wiki/Meshchersky
Site about Russian families:http://www.russianfamily.ru/m/mecher.html
and many other Russian sites.
After brief searching I've not find any mention of your father in the Internet sources but of course the Web is not the main place for research.
Could you please provide us with additional info on your father? Where did he live? Whom he was married?..Probably it'll be easy to search with such info.
