He resided in a house next to the Ulriksdal Palace, where he reportedly lived in "Oriental luxury" and arranged parties with women dancing with veils, who were allegedly then trafficked for prostitution via the white slave trade to the Russian Empire.
According to a contemporary description, he was: "Insinuative, good-looking, small and dark, with burning eyes, extremely accommodating and polite to the ladies and keeps himself in the first line always".
It was reportedly Ohan Demirgian who suggested the Polish countess Graciosa Krasińska as candidate for the second marriage of Charles XV, rather than Thyra of Denmark or a Russian Grand Duchess.
The plan was to give Krasińska the befitting status for a non-morganatic marriage by making her stepfather a Spanish grande through her relative, the Spanish monarch, and then award him with the title Royal Hignhess by the Italian monarch: thereby, Krasińska, would become Hr Royal Highness Princess Maria and acceptable as Queen of Sweden after marriage to Charles XV, with their potential son heir to the Swedish throne before the brother of Charles XV.
These plans were not popular among the royal house nor with the Swedish government, and foreign minister Baltzar von Platen made preparations to prevent the marriage.
