Hello Grand Duchess Bella--
I may have some of the answer to your question. After a bit of websurfing, I found that a Princess Natasha Kathleen Romanov was born on February 2, 1993, in San Rafael, CA. Her father, Andrei Andreevich, is the great-grandson of Grand Duke Alexander Mihalilovich, known to his family as Sandro, who married Nicholas II's oldest sister Xenia.
And coincidentally, February 2--a.k.a. Groundhog's Day!--happens to be my birthday as well!
