The use of the letter X at the end of Cajun last names can be traced back to French influences in Louisiana. Many Cajun last names are derived from French surnames that end in -eau, which, when pronounced in a Cajun accent, can sound like -eaux or -eaux. Over time, these last names have evolved to be spelled with an X to reflect their unique Cajun pronunciation and cultural identity.
Not necessarily, Italian last names can be spelled with a vowel at the end, but not all Italian last names are spelt with a vowel(s).
