Alright, so Antoinette has a rather large family on her father's side, unfortunately none on her mother's because she was an only child and her parents (Antoinette's grandparents) passed away when Antoinette was a toddler.
Bolded names must be kept. The rest are changeable. Play-bys are mostly unchangeable. However if you have one that you like better that fits with the family, PM me to discuss it.
