Sort of the same thing happened to my mom's family. Her grandparents immigrated to another country (not US) and the natives were very hostile to them because of their last name. They changed it to a native sounding last name and were able to integrate into society. However, on her side of the family, some of the relatives choose to go back to the old last name, so when we have reunions there is a mix of people with the native and original last name.
