Dear friends, Happy New Year to all!
Some minor corrections. You little a bit confused two second-cousin nephews;).
Anna's father was another man, not Sergei Ivanovich Taneev (1856-1915), who was a very famous Russian composer of that time and Tchaikovsky student and friend. You can find a lot of his works through the Internet.
Her father was Alexander Sergeevich Taneev (1850-1918), a functionary of a high rank and in addition a composer, but less known and with rather lower musical degree. By the way, he was a student of another great Russian composer Rimsky-Korsakov. Sometime ago I was searching through the internet his musical works, but haven't found anything;( Even in the Russian internet.
Sergei Ivanovich Taneev and Alexander Sergeevich Taneev were relatives, they were second-cousin nephews.
Also, as I clearly understand morvilaRomanov was asking about Anna's brother:
Taneev Sergei Alexandrovich (19.2.1886, Saint Petersburg - 1975, New York).
He was a rather simple man, compared to both nephews. And worked as a organiser of a different Court ceremonies.
Was married on Princess Tatiana Ilinichna Jorjadze, who died in 1990, also in U.S.A.
