I'm sort of named after my great-grandpa Izzy, since Isaac and Jessica both come from the same Hebrew sound (sort of - Shakespeare made up the name Jessica because he thought it sounded Jewish), but really Jessica has always been my mom's favorite name, partially because of Jesse James. When she was a kid, she got a kitten and named it Jessica, but my grandfather didn't want it, so he gave it to a fish store to keep the mice away, and she was like "Dammit, Dad, I'll name my kid that instead!" and then she did. The end!
