Thank you for the response. I had not spotted the 1910 census listing for the couple. The two Axels were separate individuals, but related. Axel W. and John Robert were brothers. A third brother, who lived in Michigan and died in 1916, was the father of Blanche. I think the response from Albert, below, provides the answer to my question regarding Axel W's death. I wonder what happened to Gertrude?
