This book is a study of the ways in which marriage customs changed in the new United States after the Revolutionary War. The author uses as examples the marriage of Theodore Sedgwick (1746 - 1813), great-great-great grandson of Immigrant Ancestor Robert Sedgwick (1613 - 1654), and those of several of his children.

I haven't read it yet, but it sure looks interesting!
