Here we have a young lady who was born in 1946. She is very famous for a
couple of big accomplishments, among other smaller accomplishments.
Update: It is not Ellen DeGeneres, Patsy Cline or Hillary Clinton. This young lady was born poor and is now not poor. There is a hint in the original description, though a bit cryptic.
Update II: I think the hint is more obvious now.
Update III: Some crazy Deadhead figured it out. It's
Dolly Parton!
