As of May 11, 1928, Julius von der Heyden was living at 11 Lincoln Park, Newark, NJ. This information comes from the Department of Commerce Aeronautical form for the Application for Identification Mark for his purchase of Travel Air Model 2000, NC4834, SN 418, from W. H. Emory, I believe a Travel Air dealer in Bradford, PA.

There is no data for NC4834 in the archives of the National Air & Space Museum (NASM), Washington, DC, because the airplane is still registered with the FAA and flown in Oregon. On July 10, 1928, Emory transferred ownership of the airplane to Mildred von der Heyden. Mildred was Julius's second wife. At that time the airplane had 80 hours on it. On September 18, 1928, she sold the airplane to Leslie Miller (of Millerized OX-5 fame) of Los Angeles, CA.

On September 4, 1928, when Julius von der Heyden landed at Davis-Monthan Airfield, apparently for gas, it was likely a ferry flight t to Los Angeles, perhaps to deliver the airplane to Leslie Miller who may have been in the process of buying it. Mr. Miller owned several OX-5 Travel Airs during this period.

Granddaughter Sue Rothwell says her grandfather, "... married my grandmother, Henrietta Bausenwein [first wife] in 1920 or so.  My mother, Anne Marie Von Der Heyden, was born in 1922.  The Von Der Heydens divorced around 1924 and Julius later remarried [Mildred] whom I think was from New York City.  She was killed in the plane crash that killed Julius, June 6, 1929.  My mother later changed her name to Hahn when Henrietta remarried.  There were no other known Von Der Heyden children.

"While the business card I have for Julius indicates he was a salesman for Consolidated Instrument Company, he also flew the Roosevelts around the US.  My mother told me he was a barnstormer for a couple of years and then had a job flying Teddy Roosevelt [this would be TR, Jr., the general of Normandy fame: "We'll start the war from right here!"] and she thought he flew him out west a couple of times.  He also flew Eleanor and  Franklin Roosevelt while Franklin was governor of New York State [early in his term, as he was elected in November, 1928]. Julius was a guest from time to time at Hyde Park, the Franklin Roosevelt's family home in the Hudson Valley in New York State.

"... I have his watch.  It didn't fare very well in the crash as it is dented and the crystal won't fit in the frame anymore.  It even has what looks to be old congealed blood on it.  I think from the NYTimes description of the nose down collision with terrain and the sad shape his watch is in, he probably had a nasty and sudden death."
