First of all, a thread on this topic already exists, if it wasn't lost on the AP site makeover some years ago. Hope it can be pulled up by someone resourceful. Since it was roughly seven or eight years ago,not only were there definitely people alive then who remembered the Romanovs, but there were personal anecdotes about them (both the Romanovs and their contemporaries) contributed to the thread. Most fascinating.
And, Maria Sisi, there were indeed multiple documentaries , generally pre-2000 which showed interviews of old-timers with real personal memories of the period and the IF . I've seen them,and may actually have one or more in some form. Damned if I know exactly which ones though. Laura Mabee would likely know.
As one of those oldtimers mentioned below, I can say that I was a teenager when Olga Alexandrovna died in Ontario a few hundred miles across the border from me in New York State. Naturally I didn't note it.
Realistically, one would have to be well over 100 years old to remember the fate of the Romanovs as say, an eight year old in 1918. They would be 105 this year. And yet, quite possible.
For what it's worth, Sanochka, I can tell you that second hand accounts of those alive in the Romanovs' time are very much in existence and can be quite telling and moving, not to mention informative.
Many millions of people fall into that category, including numerous on this site with wonderful family memories of the Romanovs , including of Court life. These would be basically middle-aged or even younger whose grandparents or great aunts or uncles or even acquaintances told them of their familiarity with the Romanov era when the listener was young, say any time in the last half of the twentieth century.
All of my grandparents were in their youthful prime in the early quarter of the last century, and likely absorbed some news of the dramatic parts of the IF's life, if only as informed newspaper readers. I could kick myself now for not having been Romanov-attuned myself when I'd had the opportunity to ask about their memories.
So in a sense there are still some indirect bearers of Romanov memories amongst us. And, also, bless those great documentaries , whose producers had the sense and energy to capture those actual Romanovs' contemporaries' accounts!
