Un Otro Reto Alfabético

Names ending in "oh" are trending pretty nicely right now, mostly for boys, but definitely a bit for girls as well. The boys' names mostly tend to actually end with -o, but for girls they're more mixed--some -o, some -ot, some -ow/owe.
For some crazy reason, I felt like setting myself another alphabet challenge--for both genders.
The rules are simple: one name for each letter, and it can't be a name I've mentioned before on this blog.
