From 1927 to 1930, he was a delegate to the Carnegie Foundation's Inter-Parliamentary Union at Paris, Berlin, Geneva, and London to study methods of classifying international law.

An active man, Roy Fitzgerald climbed Mount Rainier in 1925 and four years later swam the Bosphorus from Europe to Asia in a cold rain.

In June 1934, Congressman Fitzgerald purchased a Dayton-area farm from Frederick B. Patterson, president of National Cash Register Corp.
