Cora is definitely a cool name without trying to hard.
My second favorite name from your list is Lilou, because I assume it's pronounced "Leeloo". The 5th element is like one of my favorite movies ever.
Cora is a nice name ouo;; maybe if i ever break down and buy a second copy I might make a mayor or alt named cora 'cuz I do like the name.
I've been pronouncing Lilou as "Lee-low", but that might just be because I'm perpetually obsessed with Lilo & Stitch.
