Re: Redstone Family
Dear Binnie Sen,
There is an excellent book about David Redstone (anglicized), one of the Sobranie brothers: From Siberia with Love by Geoffrey Elliott. I found a good copy on Ebay.
You can also get info on his brother, Isaiah Redstone using the family tree of the Jewish people at http://www.jewishgen.org/databases/http://www.jewishgen.org/databases/
Best regards, Roger.
