While it's possible someone could have "Or" as a surname, it's highly unlikely. Here's why:
* Cantonese names are typically based on Chinese characters. "Or" doesn't have a clear equivalent in Chinese characters.
* Cantonese surnames are generally multi-syllabic. "Or" is a single syllable.
* Common Cantonese surnames are well-established. "Or" is not found in any major lists of Cantonese surnames.
If you are trying to find information about someone with the surname "Or," it's possible:
* They may have adopted the surname for personal reasons.
* The surname might be a mispronunciation or misspelling of another name.
* "Or" might be a nickname or a shortened version of a longer surname.
