How do I find my mother?

[Tina]

Assuming she is still using the same last name, you can sometimes find people on social networking sites like Facebook or MySpace. If that fails try:
http://find.person.superpages.com/
http://www.anywho.com/
http://www.123people.com/
http://www.zabasearch.com/

Additionally, you should try asking family members... aunts, uncles, grandparents, cousins…anyone who might have any know knowledge her.
