Michael Oher
Michael Oher's story is a well known one. After attending his high school, Briarcrest, he caught the attention of several football coaches. However, his troubled upbringing with an alcoholic mother and imprisoned father left him without a lot of support, financial or otherwise. Leigh Anne and Sean Tuohy, a couple with kids at the same school, housed and eventually adopted Michael into their family. His story is chronicled in the book and movie The Blind Side.
Bill Clinton
Before he was President of the US, Bill Clinton had to go through personal trials and tribulations. His biological father passed away when his mother was still pregnant. She worked and parented the child on her own until she was remarried to Clinton's stepdad, Roger Clinton. The man went on to raise Bill like his own soon and always saw him as such. Bill Clinton even legally changed his last name to that of his stepfather when he turned 15.
