Hello :) I have lost a name I thought was good once, but sadly I didn't jot it down because I had so much confidence in my memories but whelps.... I think that just meant it wasn't meant to be lol. So yeah... I now write my character names at 3 different place. My draft book I keep with me on my desk, Medibang where I will draw my character (I will have them beside the character), and Google docs where I write my novel.
All my characters have either Latin names or Old english names as my novel settings are half based on that time period. I have 1 character who is half asian therefore her first name is an old english based while her middle name is Chinese. So yeah, it really does depend on where your story is based and where they come from really. I can't really imagine a chinese character that is full white in an old english settings, I think that would not really be a good name choice, but at the end of the day It's also kinda up to the authors and what you prefer! :)
Cheer up anways! I'm sure you will be able to remember some names or find better names! I literally just search up latin male names, or old english female names. Or even asian female names on google hahaha!
