Hedwig Eleonora is at the left; Ulrike Eleonora (1636-1715) wears a blue over-dress in the center. I do not know who is to her right. The little girl between Ulrike Eleonora the Elder and the unknown Lady is Ulrike Eleonora the Younger (1688-1741).

Ulrike Eleonore is much more plainly dressed than the others in this 1691 portrait of her and her family.
