According to the Bailey & Cuny
The French Air Service War Chronology, a S/Lt Boillot was credited with an Aviatik two seater crashed at La Chapelle on March 31, 1916 as his first victory, while serving in N.49. On May 7, 1916 a S/Lt Boillot claimed an Albatros FTL South of Azannes (no credit), while serving in N.65. And on May 19, 1916 (not May 21) a S/Lt Georges Boillot, CO of N.65 was KIA, no location given. I would expect that the May 7 Boillot is the same as the May 19 Boillot, and I would guess/assume (pending further word from Bill) that the March 31 Boillot is the same individual. But the name does occur later in the book: a Sgt André Boillot was WIA on February 25, 1917 while in N.77; and presumably the same person, but given only as Sgt Boillot of N.77 shared a balloon with two others on June 24, 1917.
I would assume, unless Bill Bailey says otherwise, that the first three references to Boillot are to the same person (Georges), and the last two are to a different person (André).
