I can NOT find the Owner(s) to a Distressed Property, And I have

[Michael Dunn]

Literally looked through Every available Record on the Counties Website for a Phone Number, and even called and talked to the People who work in the .... Chancery Clerk and Tax Accessor's Offices , And still having no luck 

I know the First and Last name(s) of the Owner's, but neither has been living there for over a Year, and the Properties are both vaccant and distressed 

I am Going to do the Envelope thing, recommended via " The Driving for Dollars " where I put the most previous known Owner's Name and Address on the envelope , as well as a Picture of the actual Property on and in the Envelope 

I did look through the Mailbox, and saw that there was some mail with 2 Other People's names on some of the mail , that are NOT the Original/Known previous Owner(s) , BUT the Address of the Property is on the Mail with these other two People's name, that is on some of the mail in the MailBox

Could these be the Absentee Owner's ?

Likely a Child or Grandchild ?

QUESTION:

1. I looked up the 2 people who are on some of the mail, and couldn't find any Information ( NO Address or Phone Number's ), but yet I do have their names via their names being on some of the mail, with the EXACT Address of the Property that I'm Interested in

Can someone please recommend how to Contact and or find out who to Contact, and HOW TO find the Phone Number(s) of the Person(s) who have Authority on whether or not to sell the Property, aka the Trustee(s) ?

Thanks so much, I'm really at a loss here, on how to find out WHO to call and how to find their Phone Number 

Should I use a Reverse Phone Look up type Service ?  Are these Realiable for getting Current and Accurate phone numbers ?

Thanks much
