I have read the book as well. I trace my lineage as best as I can tell from Esther as well. My 23andme.com DNA test came back as being only 3% black, with 4% Asian-American and 93% European. It doesn't matter to me about whether I have African-American lineage, I'm just trying to sort out who Esther's parents were. I've hired a genealogist to work on finding it out, they should be finished fairly soon, I hope. They seem to feel that the Thomas Blair angle is important as well. We'll see. I did find out that Esther had 2 brothers, and she also had a daughter that she named Esther also. We'll see what happens.
