Are they any shipping records available on the internet on people that return to Europe from the Port of New York during the years 1920- 1928.
Olive Tree Answer: Neither USA nor Canada kept outbound shipping lists. However you can look for INBOUND ships passenger lists for your port(s) of interest.
See Ships Passenger Lists for more help and ideas. Also check the Archives of whatever country you believe your ancestor sailed to. You will be able to find out if that county has inbound lists and if so, what is available and where they are held.
