More help in research needed

Obama's house is sitting in a trust: Northern Trust Co, attorney Kelly Dibble. I got info that there are other properties sitting in that trust. Does anybody have addresses of these properties, legal descriptions, any info on these properties? What type of a trust is it: Charitable trust? Revocable? Irrevocable? Who are the beneficiaries? Who is listed as a trustor? Can smbd check microfish in county recorders office and get certified copies of tax payments?
