Good to hear from you. I have checked all the info I have on the Nickolay family and the only Susans I can find are my grandmother and great grandmother. It is more than likely that a Nickolay son had a daughter who he called Susan after his mother/grandmother. Susan, Fred and Rose are Nickolay family names. You need to work back from your Susan to see how she fits in. You can find out more by looking at the family website. If you send me your address I'll send you a photo of Pandora (and her ivory box)and the website details. Pandora's box is part of a marble statute by Harry Bates which is in store at the Tate.
