About this picture in Tobolsk: in some letters of the GD, there are mention of a little Tolia, child of a woman from Tobolsk who helped for the household (washing the floors). He was 6 years old. On the Tatiana's section, there is a picture of TN with - as I guess- this little boy. Here, it seems to little for 6 years. Perhaps it is he, perhaps a possible brother.
