I'm all ears. But...this doc appears to show he landed in New York from LONDON on the 9th August, 1959. If you are looking at the stamp PARIS, I also wondered about that ages ago, and it was explained as some immigration acronym. I'll see if I can find it again.
In August of 1959 Barack took the following:
1. Nairobi to Rome
2. Rome to Paris (Orly)
3. Paris (Orly) to New York (JKF).
