[Facts] Re: It really bothers me so many names submitted under the "Jewish" category are just Yiddish or Ashkenazi names
I've added "Jewish (Sephardic)" and J"ewish (Ashkenazi)". I would suggest not using these (as well as the even broader "Jewish") unless the name cannot be more accurately placed in a narrower category.
Note: if a name is, say, Yiddish, you do NOT need to categorize it as BOTH Yiddish and Ashkenazi. If you place it in the Yiddish category it will also automatically be included on the Ashkenazi page.
