Probate - Clackamas County courthouse woes

[Alex Wade]

I am interested in direct mailing owner's of property in probate.  I realize there are marketing companies that will sell lists, but I thought it would be wise to go to the courthouse before spending money on that kind of thing.  I went to the Clackamas County courthouse and accessed the list of cases, and opened up probably 7 or 8 different cases and clicked on all available links.  None of the information I found pertained to real property, (or any other assets for that matter).  

Has anyone else done this successfully and have any idea what I did wrong?
