Have you tried to find their marriage license? There is a public records volunteer at Random Acts Genealogical Kindness. Go to raogk.org Read guidelines Choose Oregon Choose E thru K Choose Klamath Co. and Terri.
Considering the birth of their first child, they were born around 1905. They were single on June 19, 1900 when they were born listed on the census for Tule Lake, Klamath, Oregon living in the same household.
The Oregon State Archives, arcweb.sos.state.or.us/county/cpklamathdescrip.html, has marriage records for Klamath County 1882-1966 . I've heard they're very helpful in finding a record. Successful Searching!
