Given names lacking an article

Fork of First words of non-redirect article titles with more than 50 occurrances by Ahecht

This query is marked as a draft This query has been published by Certes.

This query attempts to list given names lacking an article.  It's not foolproof but should be useful.  The Chinese bit filters out people such as Xu Chen, whose first name has no given-name article because it is a surname.  (Sadly, it also filters out names such as Lee which are both a given name and a Chinese surname.)
