Hello Adrienne I'm surprised how much interest this thread has caused, and how much history lay behind a name carved on a momument.
The added info on Tauni de Lesseps was interesting, but although the NYT gives her age as 86 there are other sites which gives it as 1920, also that she was born in France, and as Jacques was also in France it seems their marriage was still strong at that time.
As for Lady Grace MacKenzie living in New York without the count, the reason probably is because of world war one which had started the previous year and in which the Count was fully involved, for in January 1915 he was asked to approach the French government on behalf of an American flyer who wanted American flyers residing in Paris to join the French forces, the proposal was denied, by this time the Count was already serving as a Lieutenant, and as these excerpts from various websites show he continued to serve throughout the war. This was probably the reason his wife went to New York alone for to stay in either Paris or London would have been deemed too dangerous.
[Above Paris on the second of August 1915, the airship was gunned by AAA without visible result.
Then it was attacked by a Farman from the CRP: Sgt Deneboude made a single pass, caporal Louis Vallin fired incendiary bullets with a carbine.
Finally the airship was under the fire of Slt Jacques de Lesseps and Lt Galliot during half an hour.
The rear of the airship was slowly losing gas. The LZ79 was losing height and speed. It crossed the frontline at an altitude of 1800 meters with a nose-high attitude. It was completely destroyed when it crashed-landed in the fog. The location was "close to Mainvault, west of Ath".]
[DE LESSEPS, JACQUES B. M.

Citation::
The Distinguished Service Cross is presented to Jacques B. M. De Lesseps, Captain, French Army, for extraordinary heroism in action at Conflans and Audun le Roman, August 15, 1918. Captain De Lesseps made three successful bombing raids in one night, two in Connans and one on Audun le Roman, causing great damage. Despite the heavy anti-aircraft fire, he flew at an extremely low altitude and besides his successful raids, returned with valuable information of the enemy's movements.
General Orders 81, W.D., 1919
Citizen of France]
Also this article shows that in the last year of his life his four children were with him in Canada, but oddly Tauni is not mentioned among them, so the mystery deepens.
