Add Cavazos to your 'C' section [my father is a Cavazos]- this is a wonderful list however....I am of Sephardic descent myself. Sephardim.com is an excellent resource for beginning your research.

I was surprised to see names similiar to my maiden name: Eichelberger - listed as Sephardic. Here all this time I thought many of these names to be mostly German Jewish names.

And the spelling variants of the name:Frohm...I was adopted after birth and this surname became my new legal maiden name. You learn something new everyday...
