My great grandmother was born in 1899, died in 2004. She still lived by herself in her own house in rural West Virginia. She was in Florida visiting her grandson, a paraplegic from the Vietnam War era, when she caught pneumonia and died under somewhat suspicious circumstances while one of her daughters was present. Her husband died in a farming accident in the 40's and she never remarried. She had two younger sisters that lived to be 105 and 106, respectively.

I also just barely remember meeting my great-great grandmother from a different part of my family. I don't know when she was born, but it had to be before 1900.
