I had a Russian professor (Let's call her "Z") in the early 90's; she's an amazing lady who I admire a lot, and we've stayed in touch since then. Z knew Nicholai's sister Olga. Z's parents were Russian immigrants living near Toronto in Canada. Apparently there's a significant group of Russian immigrants living in that area. They had formed some sort of Russian military regiment-in-exile that met regularly. Olga Alexandrovna lived in the area and was this group's patron. My professor's Dad was the leader of the group for a time, so their regular meetings were at their house (and Olga, as patron, came to the meetings). Z was a teenager when she knew Olga, and was only about 16 when Olga died in 1960. Z says Olga was very pleasant and down to earth, considering her past. This all blew me away when I found out. Someone I know and admire knew Olga, who knew the IF!
