Is your feature request related to a problem? Please describe.
There is limited first/last name collections for locale dk.

% grep 'last_name' src/main/resources/da-DK.yml | grep -o '[[][^]]*]' | sed 's/[[]//; s/[]]//; s/, /,/g' | tr ',' '\n' | wc -l            
      10
% grep 'first_name' src/main/resources/da-DK.yml | grep -o '[[][^]]*]' | sed 's/[[]//; s/[]]//; s/, /,/g' | tr ',' '\n' | wc -l 
      20

Hi! There are no names for many locales. If you want to do a PR for them to add them, we would be happy to accept such contributions!
