The greatest of all family dynasties are hidden from view, expunged from the media, deleted from the history books, and almost never attract public attention. 
All of these are Jewish – Rothschild, Sassoon, Sebag-Montefiori, Warburg, Lehman, Goldman, and so many names you may have never heard of.
Here is a listing of a few of the Jewish bankers, representing perhaps only 25% of them, most having begun banking, financing and industrial operations in
 the early to mid-1800s, so an average of nearly 200 years, and many resulting in Jewish family dynasties that continue to this day, entirely out of the public eye.
