the contents of my dsgname folder can be found
here.
247 files, many of them not featuring on your list.
I think you may find you have a lot of these hidden away in pictures/races/somewhere. I'd recommend using windows search or some better tool to get a listing of all .txt files in your pictures/races, then filtering out the AI and readme files. You'll probably find a few unexpected designnamefiles that way.
You can also find a few more on my website at
