Hi. I have conducted minimal research on the surname Campaña. I know that there was a famous Flemish painter who moved to Spain, and he Flemish name translated to Campaña in Spanish. According to the information I read, this is the name that he took. I know that the name Campana, without the ñm is Italian and Spanish. I met a woman in Sacramento, CA who told me that her husband's last name was Campana and he was full Italian. My father is from Mexico, and so we spell our last name Campaña. Since Spanish is the common language in both Spain and Mexico, I am inclined to think that the last name was spelled with the ñ bcause this is how it is supposed to be written in Spanish per the grammar rules. I know very little Italian, but I do not think that that they use the ñ or accents in this language. Accents are common in Spanish. I know that there are several Italians with last name Campana, no ñ, that came to Ellis Island in New York. I know that many of these individuals settled in Mexico. I have questioned my father about the last name, but he has not provided me much information. As far as I know, my paternal grandparents and great gradparents were all born in Mexico. It is interesting that we spell our last name in the same manner, but you are from the Philippines. Please let me know if you have any further information.
