Ships Carry Many to Foreign Ports...Goes to the West Indies. The Orca of the Royal Mail Steam Packet Line sails today on her second cruise to the West Indies. All parts of the country are represented in the sailing list... From Philadelphia..... Frank E. Eagles ...
I checked the Philadelphia city directories of 1921 and 1922, they only show an Ernest H. , Nelson W., and Wilfred W. EAGLES in that city. 1920 US census shows the above named Ernest H. Eagles was from England.
As the previous poster mentioned, Frank E. Eagles actual SS number apparently was not the one you see on his death cert. (see below)
A SS number that leads with 262 means it was issued in Florida (428 means Mississippi).
