The discussion on whether or nor VIDAL is a jewish name is the most interesting. My grandgrandfather was born in Portugal as Vicente de Paula Vidal and emmigrated to Brazil as a teenager. No one is the family ever knew any information about his background. And we never imagined that VIDAL could be a jewish name until recently. We came to know that recently, through sites such as sephardic.com as well as through contact with jews in the USA. Some of them believe that Gore Vidal, the writer, is jew. But it has been clarified through many sources that he is not. It is important to notice, in addition, that VIDAL does came from the hebrew "Chain", as it has been said is this forum, but from the Latim "Vita". The Italian origin of VIDAL (and its slightly altered form VIDALE) is therefore most likely to be the case.
