Rskkiya, you are totally right; they are NOT martyr in the real meaning of that word, that is the reason why they are called passion bearears. As Bob, I felt the protection of Imperial family in my all life.
Someone tell only a saint can recognize an other saint. In the Church point of vew, it is not totally true; of course, the Church (orthodox, but also catholic, of course!!) is made of sinners. But mysticaly the Church is saint, as we tell in the Credo: I believe in the holy... Church. She is saint as the Spouse of Christ, as the Communion of all them who receive the body of Christ and for this reason are saints, as liturgy tell us. So in this point of vew, you are right: a saint - the Holy Church - recongnize other saints!!
About Alexandra: I venerate her so much, but know her mistake. And I can not understand something: in Russian, before the Revolution, there were so many REAL startsy and saints; for example the holy starsty of Optino and many other. They also made miracles, they also read in souls. Elisabeth Feodorovna was in contact with them. Alexandra Feodorovna all the time choose some people like Raspoutine, Philippe, Mitia. The Tsarevitch'illness does not all explain. She liked discuss with such "bad" bishops lile Pitirim, Varnava and other; saints bishops she dislike. So tragical...
