Shawn, you asked"Do you have any idea where John H. Atteberry died?"
I found something yesterday which you might want to check out. While looking for something else I found a listing of deaths in Logan County, IL. One of them was for a John H. Atteberry. He lived in Lincoln and died 20 May 1916. I have no idea which John H. this is at this time, but thought I'd pass it on in case it was yours.
