I spent a very productive morning at my nearest FHC, looking at film of merchant marine seamen's index numbers. As I rolled through the film, I noticed that names beginning with Mac or Mc were indexed under the first letter of the last part of the name. e.g.: MacDougall was listed under D, not M. This is worth remembering, as films cover sections of the alphabet. e.g.: Coa through Cou. Eileen
