I'm from Texas. I've heard Alaska used to be a part of Russia. Do they still speak Russian there or not anymore?

I was wondering if people of Alaska, Russian or America, who practice Russian Orthodox, practice their religion in English or Russian language? Is the Russian Orthodox community mostly Russians? In that case are the services done in Russian? Or is the community more diverse and Americans attend the services too? So my question is: are the services mostly done in Russian or English?
Does Russian Orthodoxy take Exorcism as seriously as the Roman Catholics? are they afraid of demons?

Nice answer Kelly but remember Alaska was Russian territory before America purchased it.
Nice point John, I had never though of that.
Thanks again kelley I need to start paying more attention to the professors, I thought Eisenhower bought Alaska in th 50's lol.
