Ginerva Navarre: I'm a Potterhead, and Ginny Weasley is one of my favorite character, so I had to use her name. Except for an unfortunate typo which turned Ginevra into Ginerva. Regardless, she goes by Ginny, or Gin, and even sometimes Bean, but that's mostly from her family and childhood friends.
Avigaile Kraghammer: Not sure exactly where or how I came up her name, but it stuck with me, and is the name I use most often, after Ginny, whenever I need to name a toon anywhere. After a recent race change, I choose a new last name for her based on a Dwarven city from the Geek & Sundry Twitch show Critical Role.
Nikohl Harrington: The older of a pair of twin sisters to Ginny. I liked the name "Nicole", but needed to give it a little flair since the normal spelling was taken. The Harrington surname is from a series of sci-fi novels written by David Weber known collectively as the Honerverse Books.
Kayelee Zilwicki: The younger of the twins. Kayelee is named after the character Kaylee Frye from the tv show/movie Firefly/Serenity. Again, with the extra E since the original name was already taken. Her last name is also from the David Weber novels
Alecto, Megaira, Tisiphone Cogspinner: The triplets, who are Ginny's cousins, are named after the Furies from Greek mythology. The last name comes from combining a pair of words to make something sound Gnomish. And after I named them, I actually found an NPC with the same surname in-game.
