Thanks Shellyesq,
This is definitely the man I have been looking for and also narrows down his military details, I am not very knowledgeable on the copyright rules, thanks for removing.
I believe the soldier to be - James O'Neill Private, U.S. Army 26th Infantry Regiment, 1st Division
Entered the Service From: Massachusetts, Date of Death: October 06, 1918
There is only one other option James O'Neill Private, U.S. Army 316th Infantry Regiment, 79th Division, Entered the Service From: Pennsylvania , Date of Death: September 26, 1918
Due to James landing in Boston and sister living in Brighton, I would say Massachusetts would be the best option.
If anyone can help establish his army number through any resources this would allow me to make a record request or look up.
Kind regards, Paul
