A few weeks ago I ran across some books that will interest you. The Golden Book of the Spanish Nobility is actually a six-volume set.
It is free to download and it has been an invaluable resource for researching the ancestors of my 13th great-grandparents Lope de Sosa and Ines Cabrera.
The real title of these volumes is Blason de Espana: Libro de orode su nobleza: Resena Genealogica y Descriptiva de la Casa Real y Grandeza de Espana y los Titulos de Castilla.
Ok, that is a mouthful and thus I came up with the title The Golden Book of the Spanish Nobility.
Volume III provided the clues to further research my ancestors. Using this books and others that I will share at a later date, I have been able to trace some lines up to 23 generations.
So, if you have found ancestors that were born in Spain or came from Spain then these books are worth searching.
The Golden Book of the Spanish Nobility
Here are the links to download all six volumes, but be aware that they are cut in half. Also be aware that I am not hosting these ebooks on my server and are simply linking to the website that has them.
You can also find these links on the website that is hosting them Biblioteca Digital Floridablanca
I hope that you download these ebooks and save them to your computer. Also if you find ancestors in them let me know.
