I’m writing a book currently and need some help naming the protagonist’s evil and annoying stepmother. To give you a little help…

Father: [name_u]George[/name_u] [name_m]Vincenzo[/name_m] [name_m]Hamilton[/name_m] [46]
Stepmother: ??? [42]
Stepsister: [name_f]Chantal[/name_f] [name_f]Mitzi[/name_f] [name_m]Rembrandt[/name_m]-[name_m]Hamilton[/name_m] [19]
Half sister: [name_f]Annabella[/name_f] [name_f]Grace[/name_f] [name_m]Hamilton[/name_m] [12]
Half sister: [name_f]Georgina[/name_f] [name_u]Anne[/name_u] [name_m]Hamilton[/name_m] [12]
Protagonist: [name_f]Aurora[/name_f] [name_f]Mae[/name_f] [name_m]Hamilton[/name_m] [19]

Any help is much appreciated! Middle names are optional.
