I am curious which branch of the Imperial family had use of Ropsha. Was this a private estate passed down similar to the Konstantinovich's Strelna and Pavlovsk or was it part of the Imperial property allocated to different members for their use?
In "Russia in Original Photographs 1860-1920" by Marvin Lyons, Routledge & Kegan Paul, 1977, there are photographs of GD Vladimir and GD Maria Pavlovna at Ropsha c1894, July 22, 1900 (name day of MP) and July 15, 1906 (name day of V). This is a twelve year span of their family gatherings at Rophsa. Although the estate is south of and not on the Gulf of Finland, was this where they established themselves during the season when the court was at Peterhof?
A curious footnote to one of the photographs at Ropsha. It is c1894 and Marvin Lyons has identified one of the group as Mme. Pistolekors (later Paley) and she is seated next to GD Paul.
