Consequently, every President of the US is a descendant of:

(b) Ferdinand III “the Saint”, King of Castile (second great grandfather of Pedro I “el Cruel”, rey de Castilla y León and fourth great grandfather of Juan Manuel, III señor de Belmonte de Campos) (father of Manuel de Villena, Señor de Escalona; father of Juan Manuel “el Escritor”, de Castilla, principe de Villena; father of Henrique Manuel de Vilhena, Conde de Seia; father of Fernando Manuel, Señor de Belmonte de Campos; father of Juan Manuel, II señor de Belmonte de Campos; father of Juan Manuel, III señor de Belmonte de Campos);

(g) Juan Manuel, III señor de Belmonte de Campos (fourth great grandson of Ferdinand III “the Saint”, King of Castile);
Because Alfonso IX “el Baboso”, rey de León y Galicia is a grandson of my 26th great grandfather, Alfonso VII, “the Emperor”, King of León and Castilla (through Ferdinand II of León) and James I “the Conqueror”, King of Aragón is a great grandson of Alfonso VII, King of León and Castilla (through Sancha of Castille and Peter II of Aragón), every US President is a descendant of Alfonso VII, “the Emperor”, King of León and Castilla and a cousin of mine!
