To beat a dead horse, here's the quote from Massie's "Fate of the Romanovs"
Mr. (Tikhon) Kulikovsky, however, refused to cooperate. When Ivanov wrote to him, explaining the purposes of the investigation and asking for a blood sample, he received no reply. Ivanov tried again through Bishop Basil Rodzianko of the Orthodox Church in America, and, finally, through Metropolitian Vitaly, the head of the Russian Orthodox Church Abroad. Ultimately, Kulikovsky replied to Ivanov. "He told me he believed this whole bones business was a hoax," Ivanov recalled. "He said, 'How can you, a Russian man, be working in England, which was so cruel to the tsar and to the Russian monarchy?' He said, 'For politican reasons, I will never give you a sample of my blood or hair or anything.'" Ivanoov was disappointed, but he did not give up. "At that time, it was critical," Ivanov said. "He was the closest relative. I spent a lot of my own money talking with him and his wife by telephone, assuring them that I was not a KGB agent. And they replied, 'Then probably the only reason for your investigations is to prove that Tikhon Nicholaevitch is not of royal blood.'"
So my query was, was there somebody else that was making this claim besides Tikhon and Guri? So obviously, yes, the discussion turned inside out and I apologize.
