Dan Ellis, San Francisco, CA

This cannot be done on the Internet, without a source of info.

What is the relationship between this person and you?

We are engaged, but I cannot locate his home address through reverse phone lookup. He has been gone 3 years and trying to get some background on him. We have maintained contact through emails and by phone.

I'd hire a licensed private investigator. How long has he been gone?

You are engaged to him. Are you in the US?

Where did he last live? I have some sources.
