Any ideas on how to find a family member I have lost touch with? I have searched the social network sites?

Ask your other family members - even if you haven't talked to them if years. Try and find them/their contact information, and see if they can help you track down the person you are missing. That's probably your best bet.

try people.yahoo.com to scan nationwide then by state.

call the library where he/she used to live and ask them to pull a cross reference on their street and get neighbors phone numbers - call them

call old places of employment and try to get forwarding info

go to blockbuster and convince (bribe) the guy behind the counter to look them up

hire a professional skiptracer

get a job at the IRS and look them up yourself

place an ad on Craigslist

are they rich - try doing a skiptrace with American Express.
