Several pages indicate he was 'half-Russian', and also 'italian', and here are some old newspaper articles:

A SON-in-law of the late American poet Ezra Pound has been charged with gun-runnng. Prince Boris de Rachewiltz degli Arodji, a respected Egyptologist and occult expert, has been accused - with 13 others, all Italian - of furnishing guns to one of the most powerful Neapolitan Camorra gangs, and to African governments and private armies.
Two of the defendants under investigation by a Milan prosecutor are accused of recruiting mercenaries for African wars.
The indictment says that Prince Boris was brought into the Milanese arms-trafficking circle "for his connections in international diplomacy, and was to open up the way for an African market, procuring, it was hoped, a means of exporting which would elude the control of customs officers."
As well as being the poet's son-in-law (he married Pound's daughter, Mary), a professor of archeology and an Egyptologist,the prince is also grand master of a quasi-masonic organisation called the Order of the Iron Crown.
Now aged 65, he was born in Rome and is officially a resident of Senegal. But he is usually found in his castle in the Tyrolean mountains around Merano, near the Italo-Austrian border.
Prince Boris allegedly acted as a high-class courier for the gun-runners, although it is not clear whether he travelled with guns among his archeological finds, like Indiana Jones.
The case dates back to the chance discovery of some parts for Sten machine guns at a mechanic's office in Pordenone, in the Fruili-Venezia region, in 1983.
It is alleged that two of the accused, Antonio Mocca and Mario Mari, provided mercenaries for "pre-selected wars and causes" in Africa. The mercenaries were said to have been recruited in Italy through a newspaper advertisement for "young volunteers willing to voyage in Africa".
a 1996 obituary for his mother in law, mentions:
