The first name I think would be “Jay”. It sounds soft and I’m a big sucker for names that start with “J”. I also like the mental image I get when I say it; I've always wanted wings and to be able to fly.
The last name is harder to choose. To me, most last names don’t really flow; they sound rough. Not to mention most last names I know belong to people I know personally, and taking someone’s last name feels weird, like I’m saying I want to be part of them, like I’m saying “You guys are family!” In reality, I don’t feel like that with most of my real family, and I hate signs of sentiment when they are illegitimate. This means I need to use a name that doesn't belong to anyone I know. That takes away most of the last names I know.
I like “Hartnett.” It sounds like “heart”, and “net”. A “heart net?” I’m not typically the type of person who likes that kind of mushy stuff, but it makes the name sound more personal- and if you feel somehow connected to the author you’re more likely to be interested in reading the book. People don’t give books a lot of time when they’re looking through shelves for something to read- you only get a brief chance to catch someone’s attention and interest. I’m not a business person, I don’t think of it as a sales tactic- I think of it as wanting to share the stories and adventures I've experienced with others and see what they take away from it.
For “Hartnett” though, I think I’d maybe just use it for a female pen name- if I haven’t used that name for a character yet anyways.
For a man, I think maybe I’d use “Kendrick.” When I was a child I had a friend with the last name “Kendrick,” but I don’t know him anymore so I wouldn't feel weird using that name.
In reality, I don't really know any other last names apart from over-used ones I constantly read in novels.
Honestly, I think I’d just stick with one name, regardless of gender:
