Great info, I know that we have a grandfather dated back to 12 century named Fernando de Cunah. You seemed to have a wealth of information. I am interested more in the name of Fernando. My father's fathers' name since passed is Robert Acuna JR. His father since passed named Ferdnando Acuna. I have a five century gap which I can not find any information. If you know of such a book, etc. Please email me back so that I too can understand and find my Royal herritage.
