I am also trying to find out about the bodyguards of the Czar. I've always been told that my Grandfather was in the Czar's bodyguard, but that was just the term given to close contacts and land owners. My grandfather's name was Vladimir Sergei Olive. He was helped to escape during the Revolution, but his sister who was a lady-in-waiting to the Czarina was not so lucky. His name was changed when he got to the US, and it was difficult to understand my grandmother when she spoke about the previous name. (according to my mother)If anyone has found that name through their research, I would certainly appreciate some information.
