Book Search: Sotelo

I'm trying to find out who knows anything about this book. Please
contact me directly: makas@nc.rr.com

"Sotelo, Fundador del Apellido en Nueva España"

This book is supposed to be used as a source by Salvador Cabral Valdez.
I'm wondering if anyone on the list is in contact with him? If so I
would like to find the name of the author and double check on the
correctness of the title. It seems I can't find it anywhere on WorldCat
or Amazon.com and that is very unusual.
