Olivia is great! Cousins is perfect and really, we could put her on either side of Charlie's family depending on what you want to do with her. Charlie's mom passed away when she was young, but I've always said that she had a sister out on the West Coast and they could be related through her. Otherwise, her dad's family is initially from New York, even if Charlie was born and raised between Boston and DC. There was an age gap between her mom and dad of roughly 14 years, which isn't entirely relevant but just a fun fact
