Yesterday I found a rich, but not quite exhaustive, resource for soldiers killed in WWI. It is a three volume book series called Soldiers of the Great War (1920) by WM Haulsee and it is digitized and available online at Ex Libris Rosetta.
The series has thousands of portraits of US casualties, categorized by state. The North Carolina section has 560 portraits and I have noticed a few from Wilson County… but it is missing a Wilson native, Distinguished Service Cross (US) and the Croix DeGuerre (France) recipient and KIA, Lt. Robert Anderson.
However, even if some are missing it is still an invaluable resource for a war that was know for its staggering amount of pointless bloodshed that shocked the world and led to a lost generation of young men.
