Yes, it's in French. Title : Les Princes Youssoupoff and Les Contes Soumarkoff-Elston with a foreword by Pr Michel Romanv, Paris 1991. I believe it was self-published; therefore, a limited number of copies. Many of the photos are Collection of Mme Xenia Sfyris. It is a good book to have but it also contains several factual errors. This is true of any history. I don't know where it can be obtained now.
