from Haaretz …..According to the Daily Telegraph, the WikiLeaks document says Prince Philip claims rights to the building based on his family connection to Sergei.Marriages among European royal stock were once common, and so it is not surprising to find that the only living descendent of the 19th-century Russian prince who gave his name to the Jerusalem building is the 21st-century husband of Britain’s queen.
Tzipi Ron, of the Society for the Protection of Nature, says that a relative Elizaveta Fyodorovna, who was Sergei’s wife, is an ancestor of Philip on his mother’s side.
It is believed that Prince Charles, Philip and Queen Elizabeth’s son, first raised a claim to the property in the 1980s. The WikiLeaks documents now reveal that demands for the property persisted until recently.
