Is it possible to find my cousin?

[Sarah]

So today I was at my great grandma's funeral and I met her great, great nephew. All I know is his first name, school, and that he's a distant cousin of mine. I would really like to find more info on him, like a phone number, email address, facebook, or twitter just so we can speak. This funeral has opened my eyes to how I really don't know people in my family, and I would like to start with him. I don't even know his mom's name, or which aunt he branches from.
Is there any way I could find out a phone number or email address so I could talk to him?
