This is wonderful information!!! Yes this is the family line. Per Amelia's daughter (Mattie Adaline Carr-Chavis) she wrote a paper called India's Children. In it she wrote:
Lizzie married the son of a white doctor. He knew that she was Negro, but since she had too many Negro friends, they moved to St. Louis to live as white. -Fannie - married a photographer, later divorce and moved with Lizzie in St.Louis and lived as a white woman.
I believe the photographer's name is JT Ball Photograhic Studio in Cinicinnati because we have pictures of Amelia India and I think Fannie, that were taken by him.
I have census information on Amelia when she moved to Maysville, KY and married George Carr, part of the iinfluential Irish slave owning Carr family.
All of this information is in my family tree.
Are you part of the Cage family or a reseacher?
Can we talk?
