While perusing Amazon.com some time ago, I saw that Louis Mendola will be releasing a new book on Sicilian Genealogy and Heraldry in November. This is a welcome addition to the list of reference books on Italian genealogy.
Sicilian Genealogy and Heraldry by Louis Mendola
While the reviewer's likening of the author to Rambo or Indiana Jones is more than a bit pretentious, it would be wise to look beyond this and give this new reference a chance. Mr. Mendola is well known for his work within this field during his long and illustrious career.
