I have also heard of that book, but do not know who is the author.
My name is Judit (in the family context Jodie) Arellano, I'm from Catalonia, Spain. I am the daughter of Jose Arellano Franco, from Andalusia, Spain. My father is the son of Antonio Maria Arellano Arellano and Encarnacion Franco Arellano (both cousins) which in turn are descendants of Tristan Arellano.
I have understood that the latter lived in Mexico, please if anyone knows anything about Tristan Arellano could give me information?
