This is a great reference book with probably the best Bibliography of
Genealogical books on specific surnames available in the world (just my
guess). The bibliography alone is 112 pages long.

the name of the book is:

"Hispanic Surnames and Family History"
by Lyman D. Platt, Ph.D.
1996 Genealogical Publishing Co., INC;
ISBN: 0-8063-1480-X

try doing an interlibrary loan on it. Or if you need I can do a specific
surname

look up in it and see if a book has been written about it.
