From A Lifelong Passion
KR, diary 28 May 1907
'Tatiana [his daughter] came running to me, very agitated and with tears in her eyes, and whispered in my ear, so her brothers wouldn't hear, that her friend and contemporary Maria P[avlovna] is engaged. Maria wrote to her from Peterhof that her fiance is the Swedish prince, the second son of the Heir, so Maria, who is three months younger than our Tatiana, is going to be married....Let it now be our daughter's turn. But I somehow wouldn't want to let her go abroad. What about Misha?!'
I had posted about Tatiana K's feelings for Prince Bagration and how it was written that she was 'wasting away' for love of him when it didn't seem like they could marry. I can't remember the thread and I thought I'd gotten it out of A Lifelong Passion but it wasn't there.
