How to find phone numbers with a known address...

[Bill Knaffl]

I am interested in trying to find a few numbers. I have a list of known
past addresses, but need to find thier phone numbers. Does anyone have any
ideas about where to start with this?
I have heard that there are various online databases, but have been unable
to find anything like this todate.
Any ideas??

Thanks in advance
