How can I locate my brother?

My older brother and I were seperated when I was five years old. I need to contact him to let him know that our mother has died.

I could hire a ‘PI’ to do a skip-trace, but before I do that I thought I would ask the smartest people in the world (Dopers!) for advice. I have an incomplete address for him from eight years ago. Where do I go from here?

Any thoughts or advice would be deeply appreciated.

Hey, I’m going to drop you an email…
