Personal names "today usually comprises a given name bestowed at birth or at a young age plus a surname. It is nearly universal for a human to have a name; except in rare cases, for example feral children growing up in isolation, or infants orphaned by natural disaster for whom no written record survives.[citation needed] The Convention on the Rights of the Child specifies that a child has the right from birth to a name. Certain isolated tribes, such as the Machiguenga of the Amazon, also lack personal names." (http://en.wikipedia.org/wiki/Personal_name)
Personal names to not include names of fictional characters, e.g. Sherlock Holmes.
Sep 29, 2016: The comment that including the wikipedia definition of personal name is not to be interpreted in a way that restricts this class to only contain strings of letters. A numerical or alphanumerical identifier that denotes a human is being is a personal name, too. (MB)
