I am looking for information about James Dawson, born about 1845 in Ireland and and naturalized in this country in 1881. He married Clara McCourtney, a native of Ohio. They were in Colorado by 1885. They have been difficult to locate in the census records but were found in 1920 in Clover, Mesa County with son James (age 35) and daughter Annabelle (22).

James died sometime between 1920 and 1930. His wife Clara and son James were still on their ranch in Mesa County in 1930, and Clara died sometime after 1942.

I would like to find a death date for James and Clara or any other information about their life in Colorado.

Thank you.
