Regen names

Do you guys know if the is any file that includes more names to the database of newgens?

Or is there still a file wich i can change to add names?


In example; i had a newgen with the surname 'Hasselbaink'. I did not like it because of Jimmy Floyd Hasselbaink.
I changed the surname through in-game editor to 'Hakke'. Later on i saw the name of Jimmy Floyd has changed to 'Jimmy Floyd Hakke'.
Would like to change without this happening. Any ideas?
