The 13 bloodlines that rule the world from the site linked at my last post:
Rothschild (Bauer or Bower)
Bruce
Cavendish (Kennedy)
De Medici
Hanover
Hapsburg
Krupp
Plantagenet
Rockefeller
Romanov
Sinclair (St. Clair)
Warburg (del Banco)
Windsor (Saxe-Coburg-Gothe)
NOTE: could be that this may not be the complete list and some very powerful lineages are still unknown to us.
Rothschild is the most visible and most often mentioned
DuPont?
