Dena reminds me of the word mean, Devlin Travers, to cross the devil. Pig is Pig, Mouse is Mouse, Malley is from O'Malley. Simple enough.
I pulled some names out of an imaginary hat. There is no character based on any person, all are a combination of many characters blended with a figment of imagination.
*There was one name that was changed the night before the final edit was submitted. It occured to me the name was too close to someone I know in Howth and she may, possibly, think that I named the character based on hers. I didn't, but to avoid all confusion or emotional misgivings, I hit replace all button and changed the characters last name. I'm glad I did.
So that is the naming game. It has been fun.
