First of all, I can be no help to you, I'm sorry, but, I went online hoping to get info. Anything at all on this family, My son is about to marry a Chaikowsky whose family originally was from Russia to PA/IL.
My future dau-n-law says they are supposed to be descended from the composer's family. We know he has no descendants, but, from possibly a male sibling.
Am interested to know if you have found anyone with information. I would like to be able to give this to my future dau.n law, as a gift. Her Dad is 84 yrs. and lives in the Keys in FL, as does she & my son. Her Dad is 1st generation American, but, one or two siblings were born in Russia. He doesn't know where, nor the spelling of the name before America of his father nor mother's name. Her name: Putalowski or Paulalowski.
