The second link takes you to the definitions of the ethncity values.
The current USA variables are set to:
4,5,0,71,1,27,2,2
4 is the continent. Ignore this, do not change this.
5 is the baseball quality. It is set to the highest value, do not change this.
0 is the 1st ethnicity. It is set to US. A better name description may be Modern US.
71 is the % of the population of the first ethnicty.
1 is the 2nd ethnicity. It is set to Hispanic.
27 is the % of the population set to Hispanic.
2 is the 3rd ethnicity. It is set to Japanese.
2 is the % of the population set to Japanese.
If you want a more historical US population, change the values to this:
206,The United States,U.S.A.,USA,American,4,5,39,71,0,29,,
With this, you are going to get an overwhelming number of century old names, and 1/3 of the names will be from modern census data. You will get just a tiny handful of Hispanic, Japanese, Chinese, etc. If desired, up ethnicity #1 to an even higher percentage.
If you want to use your own name set, locate the two name files, select all names from nameset #39, delete, then replace with your data. Then edit the nations.txt line for the USA to use nameset #39 similar to my example.
