I mean, they’re so different that it kind of works (it’s not like 2 are similar and one is the odd one out), but it’s not super cohesive. I don’t love any of those names on their own, but I also don’t mind any.
[name]Connelly[/name] - very Irish, somewhat uni, very surname-ish, I would kind of expect it to be a family. Nn [name]Connie[/name] is dated but OK, like nn’s [name]Nell[/name]/[name]Nelly[/name].
[name]Moriah[/name] - very Hebrew/Biblical, feels faintly uni for some reason as I think I’ve seen this mentioned as a male name a la [name]Elijah[/name] and [name]Isaiah[/name], seems like it would forever be confused with [name]Mariah[/name]. No real nn options? [name]Mo[/name]? [name]Mori[/name]? Probably my least favorite of the three.
[name]October[/name] - has a nice enough sound, faintly uni, I would really expect the child to be born in that month. Tober or [name]Toby[/name]/[name]Tobi[/name]/[name]Tobie[/name] seem like the nn options.
Somehow evokes [name]Cornelia[/name], [name]Maria[/name], and [name]Octavia[/name].
