Just noticed this thread today. Am wondering what your relationship is to this John McConville. I am also searching for information about him, he would be my great-uncle. He was a brother to my grandfather Tom McConville.
I did find a little something today. According to an online source he died in Pueblo "at a local hospital" on October 4, 1926. Am still looking to see if I can find anything else.
Sincerly, Judy
