Our aim here is not just to be correct, but to try to do effective interviews. I think I've learned that courtesy titles can help assure guests that while we will ask challenging questions, they will be treated with audible respect. Not only the secretary of state, Dr. Stephen Hawking, Ms. Jodie Foster or the mayor of London, but people who have lost their job or just won a moose-calling competition. Other interviewers may have different ways of doing this.
Often a guest will say something like, "My father was 'Mr.' — call me by my first name," and I try to comply. As my wife points out, I've interviewed an awful lot of people by now, sometimes several times, who think of me as "Scott." We work in an intimate medium.
Prince Karl Emich of Leiningen (born 1952), recently converted to the Orthodox faith ,  is the latest pretender to the Russian throne under the name of Prince Nikolai Kirillovich of Leiningen. He is the grandson of Grand Duchess Maria Cyrillovna of Russia , (sister of Vladimir, and aunt of Maria Vladimirovna), and great-grandson of Cyril Vladimirovich, Grand Duke of Russia . The Monarchist Party of Russia supports Prince Nikolai as the heir of the Russian throne, since they are of the opinion that Maria Vladimirovna Romanova and Nicholas Romanov are not dynasts.  In early 2014, Nikolai Kirilovich declared himself Emperor Nicholas III (successor to Nicholas II ).

That was fun…my writing has been of a personal nature of late, and I am not stunned by my titles, last 2 were “Celebrating Small Victories” and “What I Want Versus What I Do.” Any suggestions, based on nothing but the titles.
Portent suggested these: The Hunger Games Guide to Celebrating Small Victories, and
15 Freaky Reasons Why What I Want Versus What I Do Got Me Fired and Divorced [ my version of Portents suggestion]
I will give more thought to titles from here on out. I often just slap something on.
