How to find out about an owner in a foreclosure

[Curran D Bishop]

I'm trying to find out more about a foreclosed property where the owner listed is "U S BANK TRUST N A TRUSTEE."

I couldn't find much from googling that, so I looked up the mailing address and reached a law firm that said they can't give any info out. 

How do I find out who to contact? 

Thanks!
