I’m not into ACOTAR, so I didn’t even know there was a [name_m]Lucien[/name_m] there. While it’s popular now, it’s only within a specific circle of readers, and not the kids generation at all, so I don’t think it’s a big worry? It would be different if it was a made up name like in other series.
[name_f][/name_f]On [name_m]Lawrence[/name_m], I don’t think anyone born near the 21st century thinks of [name_m]Larry[/name_m] as a nickname, or even uses it as a name. [name_m]Ren[/name_m] is a great nickname, I think it’s quite realistic to use it. Maybe a different spelling would help the feeling? [name_m]Lorenz[/name_m], or [name_m]Lorenzo[/name_m], [name_m]Renzo[/name_m]. It’s funny it’s one letter off from [name_f]Florence[/name_f], yet feels like a world away from it.
[name_f][/name_f]You do seem to love the -ence sound, I hope there’s something that can be worked out with that for you.
