The von Engelhardt sisters

[Joseph_Kaiser]

During one of searches through the Yussupovs family tree, I came across Tatiana von Engelhardt (Potemkin's niece) so I decided to check on wikipedia  to learn more about the family.  There were six sisters, Barbara, Alexandra, Anna, Nadejda, Catherine and Tatiana.  The portraits of Catherine and Alexandra are wonderful, Catherine's portrait on wikipedia I think is done by Lebrun.  Two of the sisters, Alexandra and Catherine were rumored to be lovers of their own uncle!
