Wonderful picture in reply 814!!
About this old one with Tatiana and Olga perhaps mourning: no relatives died in autumn 1913, but when they were in Livadia died Dediulin, an aide-de-camp of the Tsar. It was the 26 october, and a requiem immediately took place. Then the 29 the family assisted at the funerals. It is only a guess of mine!
