This book is a biography.  I thought it was a Discovery book, but looking at the available titles from that series, I cannot figure out which one it is.  It is a biography of a woman.  She was either a niece of Henry Clay, or the Senator was family friend, so she might have been a child in the 1830s or 40s.  One of the chapters in the books describes her and a friend getting into trouble, because they wanted to be fancy and they made hoop skirts out of willow branches.  Also, maybe a chapter about playing at her father’s flour mill making cakes and pies – but maybe they were mud pies?

Thanks for any leads you can offer!
