Twain is quoted in a newspaper interview that appeared in the New York Times on Nov. 11, 1883 stating he is in favor of an international copyright law. He furthers adds "So was my great grandfather--it was in 1847 that he made his struggle in this great work--and it my hope and prayer that as long as my stock shall last the transmitted voice of that old man still go ringing down the centuries...." Which great grandfather is he alluding to? And any recommend sources that detail this? Barb
