When I moved into where I live now, some 23 years ago, I had a dog named Katie Z Wolfe. I put the phone in the dogs name as a way to screen calls and remain unlisted except to who I wanted to have the number. It wasn't until about 15 years ago I decided to pick out a fem name and what better than the one already in the phone book. I have since changed the listing to my bizness, but I kept the fem name for myself.
