Use the social networks like Friendster and Facebook
1st you need to be a member, fill up the required data and at least a picture of yourself
2nd search for "friend" bcuz you can't search for relatives.
3rd search by name, not by email address, use 3-4 names, change the sequence and/or spelling
4th when the reply is displayed, go through each possible recird
there isn't a quick way to make your search, it has taken time for me, i'm still searching
Good luck and regards
