The letter “ñ” is very special, very few words contain this type of letter and practically in Spain its sound has been maintained. Italy, France and Portugal were some of the countries that used this letter, but its phoneme has been replaced by others of equal similarity.
That is why we cannot find many names that contain the letter “ñ” and much more if it has to be by its initial. Basque names, due to their sonority, are the ones that most contain this grapheme, so it has not been difficult to find all these names in this language.
