Hi Richard, Before you can look up an obituary, you need to know when and where they died.
In 1936-37 Sherman and Elizabeth Stroup lived 2018 N 5th. Source: Polk's Coeur d'Alene, ID City Directory, www.ancestry.com.
In 1938-39 Elizabeth Stroup (widow Sherman) lived 2018 N. 5th. Source: Polk's Coeur d'Alene (ID) City Directory, www.ancestry.com. and in 1940 too.
An Elizabeth Stroup b. Aug. 15, 1866 died Oct 28, 1944 Coeur d'Alene, Kootenai Co., ID per death cert #141009. Source: BYU Idaho College, http://abish.buyi.edu/specialCollections/http://abish.buyi.edu/specialCollections/ .
Now you can request a copy of her obit from a volunteer at Random Acts Genealogical Kindness. Go to www.raogk.org, read instructions, choose Idaho, choose Kootenai Co.
If that doesn't work, contact the Coeur d'Alene Press, 208-664-8176.
