Can our website name on homestead be edited to match our domain name?

I would like to have our domain name (euccvalleycity.org) match our website name. Is it possible to do this without starting over entirely from scratch? If you type in the domain name it goes to the correct place. But if you just google search you get the website name, which is different and confusing to people. Our church website is named bbcambrosejr.homestead.com.
