found a listing for Catherine O'Donnell
Note:died - wife of John
Could not find an obit for John, (although they do have a listing for his probate)
If interested in obtaining the obit for Catherine, there is a form onhttp://www.uwstout.edu/lib/archives/arc_research.cfm
Fill it out and submit it.
Noticed an email address for them. You might contact them, and ask if they could get his obit for you.
