] Can anyone give a good book suggestion about the lives of the middle class and business.
The book 'Family Fortunes: Men and Women of the English Middle Class, 1750-1850' by Leonora Davidoff and Catherine Hall seems to be exactly what you are looking for!

This book was published in paperback about 10 years ago. It's a big book, with a definite social history, women's history slant. You might not find it on the bookshelf at your local store, but any good academic library should have a copy. This book was required reading for me in graduate school. The book was very well received in academic circles, so I can recommend it unhesitatingly. Hope you enjoy it!
