so doctor jones, you open the book with a story about your ancestor nancy belgrade, a woman born into slavery in 1808 in daniels kentucky and for obvious reasons interested in the power of using personal memoir to tell the national story and these stories of the people. can you tell us about your great great grandmother and her descendents and how starting this book was this personal story about these women fighting for equality. >> i also want to say thanks to harvard bookstore for hosting us. i work in an office, i'm sitting at home in my office now and on the wall, you can't see it are portraits of my foremothers including my great great grandmother nancy belgrade and when i work i am very aware and accountable to them in everything i do and i became so conscious in fact that i was writing this book about the history of women's coverage and i didn't know where they fit. for all my interest in them and all my thinking about them i never had a chance to ask them about where they were in 1920. nancy belgrade is no longer living with her daughter, her granddaughter and great-granddaugh
