Vernadskaia (1860-1943); and his sister Nina V. Toll' (1898-circa 1976).

Correspondence, manuscripts, documents, photographs, printed materials, and coins of Marii︠a︡ A. Svi︠a︡topolk-Mirskai︠a︡ and her son Nikolaĭ V. Svi︠a︡topolk Mirskiĭ. The correspondence is primarily from members of the Imperial family (such as Grand Duke Nikolaĭ Nikolaevich and dowager Empress Marii︠a︡ Fedorovna) to Marii︠a︡ Svi︠a︡topolk-Mirskai︠a︡. Most of it dates from the 1920's and 1930's and much of it is mounted in scrapbooks. The manuscripts include Basil Strandman's "Balkan Reminiscences." Among the documents are diplomas, certificates, passports and Imperial decrees dating back to 1832. The photographs include a photograph of Metropolitan Evlogiĭ and several dozen copies of Imperial family photographs. There are also many photographs of paintings, icons and architecture. The subject files consist of materials relating to the Notbek family, the Mariĭnskoe Sestrichestvo (to which Marii︠a︡ Svi︠a︡topolk-Mirskai︠a︡ belonged), and the Iverskai︠a︡ Church in Belgrade. Among the printed materials are 12 issues of "Khudozhestvennye Sokrovishcha Rossii" (1901)"Mʹemoires du regne de Catherine.."(Amsterdam, 1729), and "Thʹeâtre de l'Hermitage de Catherine II.."(Paris, 1799?).
