Hi Sue,
In the future when you post a query it is very important to include more information. A volunteer needs to know where to start (name, birth date and place) to ensure the info found is applicable to YOUR person.

I found a Cannon family in 1900 living in Long Creek, Grant Co., OR.
Abraham D. Cannon, b. MO, July 1844, marr 22 yrs, farmer.
Mary A. Cannon, b. IL, Nov. 1842, wife, had given birth to eight children but seven alive in 1900.
Effie P. Cannon, b. OR, Nov 1880, single.
Edna L. Cannon, b. OR, April 1883.
Earnest H. Cannon, b. OR, Dec. 1885.
Glenn L. Gilchrest, grandson, b. OR, Nov 1897.

I assume this is the correct family because an Edna L. Bayless in 1930 was living with her husband, Charles F. Bayless and chldren in Hood River, Hood River Co., OR.

But then there are two Ernest Cannon's who died in Oregon.
Ernest Cannon died 20 Sept 1950, Umatilla Co., Spouse=Willene, per death cert #10284. Source: OR Death Index 1903-98, www.ancestry.com.

An Ernest H. Cannon died 10 Sept 1967, Jackson Co per death cert #12916. Source: Same as above.

Before I do any further searching, I'd like to know which Ernest Cannon was yours.
