I very much doubt if the lady wearing the larger tiara (and seated between the two men) is the Grand Duchess Vladimir.

According to a number of reports, although the Grand Duchess had planned to attend the wedding, she was unable to do so as she had some sort of operation.




The dress she had made for the wedding.




According to another news report, the "indisposition" was an operation.



Despite the above reports, the Daily Telegraph 9 February 1901 reported that the Grand Duchess was present.




I suspect that this report was pre-prepared and published without checking all the facts.
