Francis Marion and Mary Henderson

Looking for information on Francis Marion Henderson who married Mary McGahey on May 1, 1888 in Washington Co., AR.

There were three children born before they were married, Grace, James S and Low.

Their other children were all born in MO before they moved to Pueblo, CO. They were Mary Mabel, Francis M,Peter H,Ruth, Joe D and Sallie J.

The census records indicate that Francis Marion was born in 1842 in MO. Mary McGahey was born abt 1868 in IN.

I am in search of Mary(McGahey) Henderson's obit so that I can see if it list any siblings or her parents. I beleve she died on August 15, 1952 in CO but I don't know what area so I can search for the obit.

Any help would greatly be appreciated.
