Hi Flora, I didn't find either one of them on the Censuses. Maybe they moved to Oregon after 1930 and that is the most recent Census the public has access to.
If that is the case, I suggest you contact the Linn Gen. Soc., www.lgsoregon.org/. Most Gen. Soc. will do research for a reasonable fee. Another source is www.co.linn.or.us/museum/genealogy/index.htm. Sucessful Hunting!
