Joe Duddleston was my great grandfather.I have quite a bit of written information about his life, if you're interested. From an article that appeared in the LaValle Advertiser I found this information:
"In 1921 Joe's second wife died, but he was again married on his 65th birthday, September 13, 1923, to Mary Gutknecht, a widow who had moved with her family from Portage to LaValle a few years before."
The article says nothing about the couple having any children together.I have never heard that he did. He had quite a large family by his first wife, Julia Sosinski.
