Does anyone know how to find a street address using the roll number ?

Where? In my area the info is posted on line, cross referenced.

Is this somehow connected to the demon that follows you from place to place?

Some hick town in northern ontario canada I know what you mean the organised town ships always list the address and the rol number etc but what do you do when they don't there going to charge money if I go to the township They always have there hand open be it for permits or land title searches LOL
