Bob,  You are beating a dead horse.   Names were NOT changed at Ellis Island.   Bureaucrats generate paper  -- that's how the justify their positions...If changes occurred at EI, there would be documentation.... but there is none.

If you go into Starbucks, and the barista writes Bahb on your cup, is there anything obligation on your part to use that as your name from then on?   Of course not.  So, if the  immigrant wais not given a legal binding order saying "This is you name from now on..."
