Hi Don, I found the family listed under Randel in the 1900 Grants Pass, Josephine Co. Census but I think you have this so I won't repeat it.
Then I found them in 1910 in Grants Pass under Randka but I won't repeat that Census either.
I found a John Ourtis Randle who died Josephine Co. 8 April 1918 per death cert #35. Source: Oregon Death Index 1903-1998. However, I wonder if the Ourtis isn't a typo for Curtis?
I'd try to get the obit for this person through the University of Oregon, http://libweb.uoregon.edu/general/gethelp.htm/http://libweb.uoregon.edu/general/gethelp.htm/ .
Addie, John P., Albert, Theodore and Cora were living in Grants Pass in 1920.
There is a Josephine County Historical Society, 512 SW Fifth St., Grants Pass, OR 97526, 541-479-7827. They might be a help with descendants.
