Changing your name won't change anything. It's too late for that. Those who think they know everything they need to know about you based on your name will find out eventually and then you'll be facing another pile of false assumptions. Do you want to know those kind of people?
There are still plenty of people who've never heard of the Lannisters or if they have, they don't care. I didn't give a shit about who your ancestors were.
