I agree.
For those who are religious, the dead are 'known unto God' whatever the name they may be buried under. But Alexei and the final Grand Duchess (whichever one she is) deserve a proper burial with the rest.
Our current discussion, interesting though it is, is academic.
My second priority (and this is entirely a personal one), is that there should be a proper memorial and commemoration service for those members of the household (Nagorny, Vassili Dolgoruky and others), who stayed with the Imperial Family and were killed separately from them. They died for their loyalty, and most, if not all, have unknown graves. Similarly, a memorial to Grand Duke Mikhail and Mr Johnson, whose remains have never been found.
Just a thought, could Bob (and perhaps others) explore the possibility of the APTF organising a memorial plaque at the Alexander Palace (in my view, an appropriate site)?
