As I usually do I did a search of all records for O. Farris Happy in Ancestry.com. Unfortunately, it did not turn up much. I then narrowed the search to Military records. Low and behold I found a record for an Oliver F. Happy listed as a prisoner of war during WWII. News to me! I immediately tapped in to Fold3.com to see if I could track down more information.
Missing Air Crew Reports (MACRs) of the U.S. Army Air Forces, 1942-1947, I was able to find a record of Oliver Farris Happy, Radio operator, member of a B-17 crew that was downed in Switzerland. The document also indicates that Oliver and the rest of the crew were listed as interred in Switzerland via a cable to the American Embassy in London.
I had not heard of air crews being interred in Switzerland, a neutral country during the war. A little research brought me to the website for the Swiss Internees Association, a group dedicated to the memory of Army Air Force veterans interred in Switzerland. Their website lists the flight of Oliver Happy:
Coincidentally, though Oliver Happy was born in Missouri it appears that he died in Montezuma County, Colorado. The very area that my husband's line is from. Odd coincidence, that. My next step is to contact the Swiss Internees Association to see if they have any more information on Oliver or his flight crew.
