Why Were The Radical Republicans Radical?

[Eva Elisabeth]

Good morning, Roger, you might be right as the sentence continues:" the 3 'R's', history, literature and other studies." I supposed the R's were initials representing words of etiquette or virtues. BTW, for the article about Mary's trips to Europe on your website there is one source mentioned as to be "Mary Todd Lincoln's travels to Europe" by Dr. W. Temple. Is this a book or an article? I unsuccessfully tried to Google it or find it on Amazon.
