Tony the Marine, once more I thank you for your unexpected reply to my observations. I am aware that reliable sources are the bedrock upon which Wikipedia is based. This is as it should be. In my response to your feedback regarding surnames of Corsican origin I mention a scholarly work by a Mexican linguist. Said study will go a long way in clearing up any doubts as to the origin of family names in the Hispanic world. I'll be in touch. Cuídate con mucho celo.   Alan1-11-1951
