Book excerpt: There's not a whole lot written about Caroline Quiner Ingalls, the mother of famed Little House on the Prairie author, Laura Ingalls Wilder. And I always wondered why. So I set about looking for her. . .in family letters, bits of biography and, mostly, through the words she spoke throughout the Little House series. The Ma I thought I'd find wasn't the one I discovered. Would you like to meet her? I think you'll be happy that you did.
