I'm guessing, his not as popular as his brother, his family or his sister-in-law Ella.
It says his a Hieromartyr, but the Grand Duke was not a priest! Someone help me with this one.
but I have seen icons here and there (rare ones, in NYC, but the people there are snobby, and if you don't speak Russian, there even more snobby, I don't like going there). of Michael, the Konstantinovichi brothers and Prince Paley.
