Is there a website where if I input the name and email of a person , it will tell me the person's current address?

Try http://www.411.com/ but with today's privacy issues what you are wanting to do is not an easy task.

If the person has a listed phone number, whitepages.com, switchboard.com or the aforementioned 411.com will likely show their address. Other than that, you can just Google the person's name.

Yes, googling someone's name "firstname lastname" OR "lastname firstname" can bring results.

Another source I sometimes use is www.internetoracle.com

www.zabbasearch.com (http://www.zabbasearch.com) is real easy to use. Just need a name and a state usually. I have been able to find all my friends with it. It is free to use.
