My grandparents Prokop and Natalia came to America via Ellis Island 1913. The ship manifest shows the last name Senkow-Senik. They used the name Raymond, until they filed for citizenship, and they began using Sennikoff. Ship manifest listed Polish as ethnicity, but they
spoke Russian. They were married in Kiev, 1913.Natlalia's maiden name was Shershen. They listed Kowalsky as last residence, but I have not found a town by this name, around Kiev.They were of Russian Orthodox Faith. Are these names Russian, Polish, or Ukrainian?
