Oldest Ansester homework (Updated)

The oldest ancestor I know of is my great-grandmother Margaret Francis. She was born in Savana, Gerogia on Jan 19 1919. Though out her lifetime, she had moved from place to place. She grew up in Savana but moved to New York in 1975. Later, she moved to Philadelphia, to stay with her daughter who was my late grandmother. Margaret died on the 25th of August of this year, and it hurt me so much that i could not be at her funeral because I was in South Carolina for the summer. In her early years, she worked as a chef. She wanted to do something that she would found exciting and would give her good money so she support her family.
I would say that she would be my ancestor, because thoughout the 13 years I've know her, she taught me many thing and one i will never forget "What is done in the darkness comes out in the light". If she was here today she would've turned 90 years old. She was a good great-grandmother and her memory still carries on. If I had one wish, it would to see her one last time.
