Does anyone have experience tracking down someone they haven't seen in decades? I haven't seen my sister (different mom) in 20 years and I'm trying to find her. I know her birthday, full maiden name and what general area she is from but she's now 26 years old so I don't know if she's moved, gotten married, etc. I looked her up on FB and did some Google searches, but I'm not really having much luck. Any tips? Thanks!
