I usually just random generate names from the internet. Or use names I really like, such as Ophelia or Daphne, if I happen to actually think of one. The exception being my Faye family, the mermaids of Isla Paradiso. I was going for both a name and a thing, so sometimes they end up sounding a bit odd. The current two mermaids of the family are Butterfly and her daughter, Glint. Glint was named after a dragon from Guild Wars, because her parents both have blue hair, the dragon was blue, and I always planned on giving her a blue tail, as well. Her non-mermaid sister is Rose, a little more normal sounding. I think I might reserve my extra weird names for the mermaids. I want them to be really colorful, so may as well give them unique names, too. I keep them all saved in a word document when I think of one.
