Thank you Nena, Shandy and others.. About new thread (indentification, questions/answers) - good idea. If someone will open it, I would join it with a big pleasure.
Shandy and Kalafrana, you both are a little bit wrong and are confusing all our dear forum members. He was not just an "ordinary soldier". He was an a officer (not lower than a Lieutenant, according to the photo) and served in the Guard's, and moreover in His Majesty (that means that Nicholas could personally be familiar with the officers of his regiment, including Kiknadze) 3rd Rifle Regiment (Saint Petersburg dislocation). Only nobility and aristocracy at that time could serve in the Guard, especially in His Majesty's Regiment. So, it means that Tatiana's favourite was a very intelligent, educated and brave officer of one of the best Infantry and Rifle Regiments of the Russian Empire with a great 200-years History. As I know, Russia at that time had only a dozen of His Majesty's (named by the Nicholas II and patronized by him) regiments in all the Armed Forces (including Cavalry, Infantry, etc.).
I also think, that Nicholas II and Alexandra Feodorovna were both well aware of their daughters flirtations. That's why Nicholas II appointed Demenkov (earlier he was a Naval officer) in His Majesty's Infantry United Regiment, closer to Maria (good father!). And especially that's why Alexandra Feodorovna allowed Kiknadze to stay in the Tsarskoe Selo hospital as a nurse and she (good mother!) sometimes was gathering together Demenkov (Maria), Kiknadze (Tatiana), Shah-Bagov (Olga) in a hospital. So, don't worry, careful parents had a total control of all the situation. And finally, they would not allowed to their girls untested and unknown men.
Sarah, Пожалуйста. Все только для тебя!
