I'm still trying to figure something out. We're both contemplating changing our last names to my mom's maiden name, which is Myrick (she has all sisters so the name isn't currently being carried on). But I also thought of just using our first names for the hashtag (Allan and Andrea) as to not confuse people...
One idea is to incorporate the "celebrity couple name" our friends use, Allandrea. We're also both cat lovers, boardgame hobbyists, and Nintendo fans/gamers, so I was also thinking of trying to fit that in. Obviously open to suggestions! I love the ones I'm seeing here!
