I've always been slightly dissatisfied with most online generators; I find them to be fairly poorly curated and contain a lot of options that I wouldn't really use. So, I made my own.
Hover over a genre of namelist in the navbar and select your desired namelist. I've sourced these names from a LOT of different places so I can only take credit for a small portion.
Note: you may need to clear your cache after the namelists are updated for new additions to show up in the generator.
