We do have some pictures of Dr. Botkin and of him with his children. Some I think were given to Marina by her Aunt Tatiana, and I think T's granddaughters may still have the major portion of them. I think that practically all pictures we have have been reproduced in various publications.
As for "papers," we have none from Dr. Eugene, so far as I am aware, unless they are copies that have appeared elsewhere and been sent to Marina in the past. It is possible again that T might have saved some letters or something. Her escape was under less pressure than Gleb's.
Gleb was, and remained on, a Bolshevik "death list" for many years - even after he came to this country. He actually made it to the Japanese destroyer under fire.
Gleb did write at least two articles for the "North American Review," one especially pertinent now about his joy at becoming an "American."
