Family Photograph 24

The artists daughters Natasha and Sonja are shown in native costumes for a festival. As Stember has done before, he included two of his portraits in the picture.  The gentleman with the white hair remains unidentified #7.  The lady is either # 214 or #48 on this site and the photo is dated 1910 in St. Petersburg. both of these paintings are very similar so it is difficult to tell.  What do you think?
