Can anyone tell me how to go about finding evidence of a surname change. I have been told that my GG-Grandfather was forced to change his Last name upon entering the US through NY from Ireland abt. 1872. For me this is a problem in that all those who might have known have passed on. I do not know the circumstances surrounding this story, only that the original family name was Gamil, Gammil, Gammel or Gamel or some such Spelling.
