Dear Nerdfighters, What Should My Last Name Be?

My fiancé and I have decided we want to pick a new last name for ourselves when we get married. We’ve found a few family options from generations prior, and heard a few random options we like while out and about. We’d like to add some more options based off of our shared interests: gardening, nerdfighteria, and Taylor Swift music. Do you have any Green bro inspired recommendations? (For example, I mentioned Lancaster and Waters to my fiancé because I’ve loved TFIOS forever.) Our first names are Emily & Christopher.
