There were many, many more than that.
I've got a book 'Over the Front' a complete record of fighter aces of the US and French air services, its got short biographies of each man, and this is just of the men who were aces in WW1.
Just opened to a random page, Harvey Weir Cook, flew with 94th aero, 7 victories, died in 1943 in a P-40 in New Zealand.
another page, Eugene Seeley Coler, 16 victories WW1, also served with the 319 Bomb Group in WW2.
There has to be hundreds of them, and that's just from the ones who made ace in WW1.
There are so many with noted WW2 service but no details, I can't list them all
