Public records show my number shared with another person

I get spammed constantly with people looking for another person and the property they have. This has been going on for years. When I look this person / property up, it shows my number on his contact information, and it also shows me being associated with it. I tracked down the person, and he is as confused as I am. I have had this number for over 20 years. It also shows that it is associated with New Cingular Wireless Pcs (ATT)...I'm pretty sure this is who I originally signed up with many years ago.

How can I get this other person's name removed from these public records related to my phone number?
