[name_f]Lavinia[/name_f] [name_f]Silvia[/name_f] [name_f]Rebecca[/name_f] is the name of a classmate. You could therefore use [name_f]Silvia[/name_f] [name_f]Rebecca[/name_f] (I like it so much) or [name_f]Lavinia[/name_f] [name_f]Rebecca[/name_f] (Very Victoriana) for example. This was my first thought.
