Hallo, Geoff. Those born in the US included Renny Dodds (engineer), Gus Weikham (barber) and Matthew Leonard (3rd Class steward). Though not strictly crew members, you could also include the three American postal clerks - Gwinn, March and Woody. Of these six, the only survivor was Weikham.
Off hand, I can't suggest a comprehensive list of all those who had at some time in their lives been resident in the US.
