You're all very welcome! I like to translate their letters for us all to read : )
Tatiana to Grand Duchess Olga Alexandrovna
December 5, 1915
(edit: LOL, I just noticed that it is December 5 today - this letter has been written 98 years ago : ))
"Poor Sonia was buried today. Mitia and Vera Orbeliani have just arrived, poor ones. There were a lot of people. It happened all of a sudden and she was taken too awfully soon - in only two days. Mama was with her all the time. She was almost unconscious, and couldn't even speak or open her eyes. However, everytime Mama called on her, she blinked her eyes, letting us know that she could still hear but could not talk.
Her aunts were here, too., and came to her every hour. Her face had changed and turned so yellow. The priest gave her the last unction, and while she was slowly getting nearer her end, he gently read the prayer for the dying. She was buried here in the Kazan cemetery.
I had just one lesson today. We have everything working well in the hospital..."
