You don't get many family names more prestigious than Rothschild, in fact in my book....there are no names more prestigious.  Not Rockefeller or any other for that matter, Rothschild is the top of the heap:

History buffs will know that it was the Baron Rothschild who negotiated the Balfour Declaration which galvanized world wide support among the world's Jewish population behind Britain and the allied powers against the Central Powers during the First World War.  Conspiracy buffs contend that the world's Central Banking system is owned and controlled by the Rothschild familly. 

I'm an agnostic on it all...but I hold the Rothschild name in high esteem. 

The Rotschild & Co referenced as having been engaged as an advisor to evaluate a possible US listing....the Chariman is listed on their site as one Alexandre de Rothschild.

Assuming that de Rothschild is not a common name, and I do make that assumption, there is a David René de Rothschild who is cited by wiki as being a member of the French branch of the Rothschild family and he has a son named Alexandre.

Don it seems may be traveling close to some pretty lofty circles it would seem....5 degress of separation?   For DM he may be just 1 or 2 degrees away from some of the richest people in the entire world.
