Hello Mrs. Judinyova,
sorry but our page is only for publishing informations about emigrants and their families. Nathalie Vogel von Friesenhof is on our page because of the emigration of her husband Anton Günter Friedrich Elimar von Holstein-Gottorp, Herzog von Oldenburg.
I send a copy of this email to the mailing-lists for Oldenburg. I hope there is someone who can help you! Have you made a contact with the Staatsarchiv Oldenburg, the Landesbibliothek Oldenburg or the Kunstverein Oldenburg? I think they also could help you.
Best regards,
Gunter Jüchter
