Make up names that sound right. We picked Kendall for our main character because it sounded right. Same for Robbie.
We did have an Aella, which was just weird. lol Thankfully we saw sense before we debuted and changed it to Emma, though it still feels off to type out her name like that when for the past few years we've written her as Aella.
It depends on your world as well. If it's earth, then you can use really whatever normal name you want, because people don't keep track of what names actually mean, unless you want to be symbolic.
