What kind of business did the Russian emigrants run after having fle? Know any?

This is my contribution to this subject:

The regular vehicle inspection that is done every year for every car here had been moved over to foreign, big enterprizes. But now it has been moved over back to Finnish actors and enterprizes.

I found this somewhat interesting as my Russian emigrant grandfather started the first car school here in Finland sometimes after the First World War. He never run the business by himself but grounded it for his sons who had returned from the war and got married and started their families. In our family it is said the war and the car school have been the reasons why my uncles didn't study at the university. My grandfather was an educated Engineer from St. Petersburg. Then the car school gave living for the whole family - my grandmother and the girls of the family. And then my grandfather moved abroad because of the security reasons for the rest of his life. Before he died as an very old man he returned, however, to Finland and died here.

During the years when he lived abroad he, however, visited us regularly. He is buried on the very old Russian Orthodox graveyard here - now very near to the big motorway - and my grandmother is naturally buried in the same graveyard though she was not an Russian Orthodox (= the Eastern Catholic Church), but had her Huguenot roots (= Christian protestants from France, who had fled from there). My relatives are joking when they use to say that now he is resting near all the cars he loved for the rest of the times. However, the cars school was not the only business of his, but he worked on some other branches, too.

There has been big changes in this bransch - the car school business. If it once was a florishing business that is not the case any more and might get more tuff all the time. My uncles later had two car schools and they have been educating also in Russish trough the years. Already very many years ago I heard that people from Russia came to us here in order to get a driver's licence that was valid in the European Union areas. That is why it is not impossible that our surname is still known at least in St. Petersburg, only 350 km from here - and maybe even somewhere else.

But there doesn't exist any more any car school with our surname as my last uncle retired as a very old man and my cousin suddenly died. But more than 10 years ago somebody offered me a lot of money for this surname of ours. Might it still have some value? Might I carry on some business with our name in the global world of the whole Russia and the European Union? And what business in that case?
