There are historical figures we have all heard of but really know nothing about.
Lets take an example Mrs Beeton. You will have all heard of her and know that she is the author of Mrs Beeton's Book of Household Management (popularly known as Mrs Beeton's Cookbook). And that's all I knew.
Except that I find she really isn't the author, most of the recipes were taken from other sources and she is really the compiler and/or editor). I've always assumed that she was a middle aged woman when she wrote the book (Well the book is a series of supplements for a magazine The Englishwoman's Domestic Magazine), so I was surprised to learn that Mrs Beeton was aged 23-25 when writing and that she died aged 28 a week after given birth to her fourth child.
Her Mother had 21 children apparently.
